1. Temperature
2. Heat Energy
3. Conduction
4. Conductors
5. Insulators
6. Convection
7. Radiation

Answer 1

1. Temperature is the degree of hotness or coldness of a place or a body.
2. Heat Energy is the form of energy, which flows from a hot body to cold body.
3. Conduction is the mode of heat transfer when two bodies come in contact and is primary mode of heat transfer in solids.
4. Conductors are substances that can easily conduct heat energy.
5. Insulators are substances that do not conduct heat energy very well.
6. Convection is a mode of heat transfer occurring due to mass movement of a liquid or a gas itself.
7. Radiation is a mode of transfer of heat energy in the form of electromagnetic waves.
