A guide to transporting out one experiment to investigate the relationship between the mass and volume of liquids and also regular solids

To investigate experimentally the relationship between the mass and volume that liquids and also regular solids, and also analyse and interpret the data gathered.

You are watching: As mass increases what happens to the volume

The key variables in a scientific research experiment space the live independence variable, the dependence variable and also the yellowcomic.comntrol variables.

The **Independent Variable** is what we change or yellowcomic.comntrol in the experiment.

The **Dependent Variable** is what we space testing and will be measured in the experiment.

The **yellowcomic.comntrol Variables** are what we save the same during the experiment to make certain it’s a same test.

**Variables**

In this experiment the:

Independent variable is the volume of the object.Dependent change is the fixed of the object.yellowcomic.comntrol Variables room the product of the object, room temperature, and temperature of the water.Remember - these variables room yellowcomic.comntrolled (or maintained the same) due to the fact that to do it a same test, just 1 variable have the right to be changed, i m sorry in this case is the volume the the object.

**Equation**

Density = \(\fracmassvolume\)

**Prediction**

As the volume of the material increases, the massive will likewise increase.

**Justification because that the prediction**

The higher the volume the the thing the greater the variety of atoms present.

This will result in the object having higher mass.

**Regular objects**

**Apparatus**

Six constant objects that the exact same material however different volumes, a half-metre rule, a optimal pan balance.

**Method**

**Results**

**Graph**

Plot a graph of massive in g on the y-axis against volume in cm3 top top the x-axis.

Draw a heat of best fit with the points.

The gradient of the graph = \(\fracmassvolume\) = density

Calculate the gradient that the graph and hence the density of the object.

**yellowcomic.comnclusion**

We have the right to see indigenous the graph that as the volume the the object rises its mass additionally increases.

This agrees with our prediction.

In fact, because the line of best fit is a right line through the origin, we deserve to be even an ext precise.

We can say that the volume of the thing is directly proportional come its mass.

As the volume rises the massive of the object increases in direct proportion.

The gradient that the graph equates to the thickness of the material.

**Cause of error**

The main cause of error in this experiment is the measurement of length, breadth and height.

This can be retained to a minimum through repeating every measurement and also calculating the average.
