Heating houses

Temperature and heat

Temperature and heat are not the same thing because: 

- Temperature is a measure of how hot something is. (Measured in C)

- Heat is a measure of the thermal energy contained in an object. (Measured in J)

Heat energy is needed to increase the temperature of an object. 

- The amount of energy needed depends on the mass of the object, the type of material it is made from and the temperature increase.

Heat energy is also absorbed when substances melt or boil, but the temperature does not alter during a change of state

- The amount of energy needed to melt or boil something depends upon the mass of the object and the type of material it is made from.

Temperature of and object eventaully reachs the temperature of their surroundings.

Energy in form of heat, flows from a warmer to a colder body.

- Putting ice cube on your hand, your hand gets colder.

- Your house will get cloder if you leave your door open during winter.

Difference between measuring heat and temperature:

Temperature is a measure of the average kinetic energy of the particles.

Heat is a measure of the total interal energy of an object. It is measured on a absolute scale.
