Answer 1

The answers are written below (in highlighted):

HEAT VS TEMPERATURE

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 and kelvin.

When matter is heated, it expands.

Few points to know about heat and temperature-

• The temperature depends on how fast the molecules vibrate as it is related to kinetic energy.
• Upon heating matter, thermal energy is provided and so temperature rises and the molecules take up more space causing the matter to expand.
• Thus, heat can be considered as the total energy present in the matter while temperature indicates the measure of this internal energy.
