HEAT
Science-7

2. Heat is the energy transferred
from an object at a higher
temperature to an object at a
lower temperature.
Energy is the form of heat
always flows from hot to cold.

3. Heat transfer is classified into various mechanisms,
such as thermal conduction, thermal convection,
thermal radiation, and transfer of energy
In conduction, heat transfer occurs between objects by
direct contact. In convection, the heat transfer takes
within the fluid. In radiation, heat transfer occurs
through electromagnetic waves without involving
particles. The heat transfer takes place due to the
difference in temperature.

4. Convection, radiation and conduction are three
different methods of heat.
1.Convection: this type of heat transfer occurs in fluids,such as
liquids or gasses.
2.Radiation: is the transfer of heat through electromagnetic
waves.
3.Conduction: is the transfer of heat through direct contact
between objects or substances.

5. That’s all and thankyou for listening
we are the group 1 thankyou!
