Q: What does temperature measure?


Read this paragraph and choose the correct option from the provided answers:

In this lesson, you read that air density and pressure change with altitude. The temperature of the air also changes with altitude. Air temperature measures the heat energy of air molecules.

 Choices:

- lowest kinetic energy of molecules

- average potential energy of molecules

- highest potential energy of molecules

- average kinetic energy of molecules


A:
average kinetic energy of molecules
