✏Heat and Temperature
==============================
Activity 1:
Complete each statement using term or terms from the list below. Write your answers on a separate sheet of paper.
Heat and temperature are related but they are not the same. Heat depends on how fast molecules vibrate and also on the number of molecules that vibrate. More vibrating molecules usually mean more internal energy. Fewer vibrating molecules usually mean less internal energy. Faster vibrating molecules mean higher temperature. Slower vibrating molecules mean lower temperature. Heat is measured in units called joules and calories. Temperature is measured in units called Celsius,Fahrenheit,Kelvin. When matter is heated, it expands.

✏True or False
==============================
Activity 2:
Write TRUE if the statement is correct and FALSE if the statement is wrong.Write your answers on a separate sheet of paper.
FALSE 1.Heat depends only on how fast molecules vibrate.
TRUE 2.Joule is a unit of heat energy.
TRUE 3.We measure temperature with a thermometer.
TRUE 4.The faster molecules vibrate, the more heat they give off.
TRUE 5.Temperature measures the average kinetic energy per molecule.
