Rohan is conducting an experiment with gases in his chemistry class. He needs to use the gas laws to predict how the volume of a gas will change with temperature. Which of the following statements best explains why Rohan must measure the temperature on an absolute scale (like the Kelvin scale) instead of a relative scale (like the Celsius scale)?
a. Absolute temperature scales are commonly used in science.
b. Relative temperatures must be converted to absolute temperatures.
c. Relative and absolute temperature scales have different values.
d. Zero on a relative temperature scale would not correspond to a zero volume of gas.
Samuel is using a bicycle pump to inflate a tire. He notices that when he pushes down on the handle, the air inside the pump is easily squeezed into a smaller space. What is the ability of a gas to be easily squeezed or compacted called?
compressibility
pressure
expandability
diffusivity
