volume length mass and density relationship

The formula that relates density, mass, and volume looks like this: The box is a perfect cube, and each side has a length of meters. Density is defined as mass per unit volume; mathematically, we would write: or mass m density d relationship between mass and volume of the substance. A graphic showing flow through a nozzle with the mass flow rate equation for subsonic For a fluid (a liquid or a gas) the density, volume, and shape of the object can all A units check gives area x length/time x time = area x length = volume.

1.6: The Units of Measurement

Any object with the same mass as this cylinder is said to have a mass of 1 kilogram. One kilogram is about 2. National Institutes of Standards and Technology. Temperature Temperature is an intensive property. The SI unit of temperature is the kelvin K. Celsius degrees are the same magnitude as those of kelvin, but the two scales place their zeros in different places. Water freezes at The conversion between these two units and the Fahrenheit scale will be discussed later in this chapter.

Time The SI base unit of time is the second s. Alternatively, hours, days, and years can be used. For example, we can use the base unit of length to define a unit of volume, and the base units of mass and length to define a unit of density. Volume Volume is the measure of the amount of space occupied by an object. The standard volume is a cubic meter m3a cube with an edge length of exactly one meter.

To dispense a cubic meter of water, we could build a cubic box with edge lengths of exactly one meter. This box would hold a cubic meter of water or any other substance. A more commonly used unit of volume is derived from the decimeter 0. A cube with edge lengths of exactly one decimeter contains a volume of one cubic decimeter dm3.

Using the metric ruler or tape measurement to measure the diameter D in centimeter of each object to two decimal points and record the data in the table 6. Using tape measurement, measure the circumference C in centimeter of each object to two decimal point and record the data in the table 6. Graphing C versus D using a computer spreadsheet program. Using linear line fit command from the program menu to plot a best-fit line.

Recording the slope of each line in the table 6. Recording the percent error in the table 6. Setting up the data like what it is shown below: Finding the mass of the bolt using a digital scale and then compare this value to the mass of the water displaced by bolt using the following steps: Be careful not to allow any water to splash out of the graduated cylinder. Taking a moment to compare the values for Ms and Md.

Finding the volume of the volt with ruler and with displacement by using the following steps: Taking a moment to compare the values of Vr and Vd. Calculate the density of bolt. Taking a moment to compare all the type of density and consider which density type is more accurate. Setting the table as what it is shown below: Measuring and marking a verticals distance of 2 m from the floor up.

Standing on the chair and hold a small box or similar object at the marked height in one hand and the stopwatch in the other hand. Starting the stopwatch at the same instant time the releasing of the falling object.

How it works - Mass, Density, and Volume - Fundamental Properties in Relation to Volume and Density

Stopping the stopwatch when the object is hitting the floor. Record the times to nearest tenth of a second in table 8. Repeating the trial to three times. Finding the average drop time of the object. Recording it in the table 8. Repeating the step of the eye opened activity, however in this time the eye is closed. Experimental Theory Physics is fundamentally an experimental science-based study that importantly aiming at the flawless result of its measurement.

In physics experiment, it is important to regard the measurement process as an essential process that need to be precisely and accurately done; every experiment, as a result, need to have a perfect-close result of its scientific measurement. By using an international unit standard, every unit that involved in physics experiment is consequently become well determined and therefore is expected to be able to create a similarity in an international level standard.

Regarding International System of Unit or commonly called as SI is theoretically a modern form of the metric system that use the units of ten as its basis in processing the experimental data number, therefore by aiming at the same standard, the physics measurement is then expected not to have a vague result in every different country indeed it should shows a resemblance and unity perception due to what measurement means and aiming for.

Length, temperature, volume, mass, and density, as a result of the international standardized, have been possessing an international unit. Length, as a variable that being used to measure the length of something, is having meter as its SI unit. In line with length, temperature has Kelvin as its SI unit. Volume has liter as its SU unit and mass has kilogram as its SI. Due to the experiment, the formula that being used are as follows: Length, Time, and Mass Measurement Table 9. Based on the observations, the calculations are basically telling that, in physics experiment, using an estimation or prediction to determine the value of certain object must definitely resulting an error.

This is fundamentally grounded by the essence of prediction Week 1, Report 2: Measurement itself; the more the prediction is used by someone on a certain case, the least possibilities of prediction error will be. Therefore, by looking at the result, it is reasonable to conclude that predicting length is easier rather that predicting mass because some people have been getting used to predicting length compared to predicting mass; and by that, it is also acceptable to say that the data of length prediction is more reliable compared to the data of mass prediction.

In short, it is important to correctly perform an estimation in this case length, time, and mass because the estimation itself is directly proportional to the value of the percent error in the experiment. When the error is big more than five percentthe data used in the experiment is consequently said to be failed or unreliable; cannot be used to determine the value of the result.

By determining the mater tape as an acceptable value, the error of the measurement using hand and ruler are as follow: However, it is in contrast to ruler and meter tape; considering that those two measurement tools are being used without converting its unit to another units, the percent error of their results is consequently less than the hand measurement tool.

Answering Questions Besides revealing the percent error due to the measurement tool that is being used, the three tables are also implicitly stating that the influence of the measurement tool to determine the percent error is decreasing when the measurement is done to the bigger object.

By doing observation, it can be shown that, when the hand is used to measure the small object hand phone the error is bigger rather that when the hand is used to measure a bigger object table. In short, hand is adequate to be used as a measurement tool is when hand is used to measure a big object.

When a variables of a calculation are altered by the chance of error, the value of the finals result of the calculation will also be shifted toward a bigger error. Therefore when the length, width, and height of a calculation is being off a little, the value of the volume will be changed toward an error.

Measurement Graph Circumference Versus Diameter 70 60,3 60 50 Circumference 40 30 21,4 20 10,5 10,8 8 10 0 2,5 3,1 3,3 6,4 28,2 Diameter Based on the observation, the shape of the graph is not linear; this is basically because the graph is made up of lines that has different slope.

Besides the difference of the slope regard the graph as a nonlinear graph, the difference of the slope in each line is also regard the error that is contained in each data taken. Density Measurement Table Measurement Answering Question In the experiment, especially when measuring the displaced water, the error is occurred; it is basically grounded by the limitation of the scale of the graduated cylinder.

When the displaced water is too small and the graduated cylinder cannot precisely read the displaced water scale, the experiment is consequently said to be occurring an error.
