| Q. |
A gas thermometer is more sensitive than a liquid thermometer because a gas: |
| A. | is lighter than liquid |
| B. | expands more than a liquid |
| C. | is easy to obtain |
| D. | does not change state easily |
| Answer» D. does not change state easily | |
|
Explanation: Gas is easily compressed so it would have a more versatile range of measurement at least in our atmospheric conditions. Liquid is not so easily compressed, so, very little pressure via mass w/ gravity or heat would cause it to quickly jump between changes. A gas thermometer measures temperature by the variation in volume or pressure of a gas. One common apparatus is a constant volume thermometer. Gas thermometers are often used to calibrate other thermometers. |
