Answer to Question #45948 in Physics for nano

Question

Farmers usually compress wool to make it more compact to transport. Wool is collected from sheep
then put under a press and compressed in a sack. The relationship between the pressure applied on the wool and its volume is given by , where P is the pressure, V is the volume and k is a constant for the set up. Pressure is measured in kilo Pascal (kPa) and volume is measured in m3.

1. Using the above data draw a graph. Make sure that you label the axes properly with units.

2. Transform the data to get a straight line graph. Put the transformed data in the table.
3. Use this data to draw a graph. Make sure that you label the axes properly with units.

4. Find the gradient of the graph with its units.

5. Write an equation that shows the mathematical relationship between pressure and volume.
