How do molecules at warm temperatures differ from molecules at cool temperatures?

• At warm temperatures, molecules move around more.

• At warm temperatures, molecules grow in size.

• At warm temperatures, molecules exchange electrons more easily.

• At warm temperatures, molecules combine with each other more easily.

What is the difference between heat and temperature?

• Temperature measures the motion of molecules, and heat is the energy of that motion

• Temperature is measured by a thermometer, and heat is measured by a barometer

• Heat is measured in calories, and temperature is measured in joules

• Heat is caused by the sun, and temperature is caused by conditions in the atmosphhere
