705 - Transfer of Heat

Heat can be transferred in three ways, there are :

• Conduction

• Convection

• Radiation

• Reflection

______________ is the transfer of energy from one molecule to another by direct contact.

_____________ is the movement of heat by a fluid such as water or air.

__________ is the transfer of heat by electromagnetic waves, which does not require any medium to help with the transfer process.

Thermal conductivity of different metals is different.

• True

• False

The higher the temperature, the higher will be the radiation.

• True
