Accepted Answer

Across

1. The transfer of heat by the circulation or movement of heated particles is called convection.
2. The colour of any object is the light it reflects. A colour which is a good radiator as well as a good absorber of heat is black.
5. The scale which shows the temperature of boiling water as 100 is Celsius scale. The freezing point of water in this scale is $0$ degrees Celsius.
6. The instrument to measure temperature is thermometer. Clinical thermometer is used to measure the human body temperature.
8. Fastest mode of heat transfer is radiation. It requires no medium to transfer the heat.
9. A material that is a poor conductor of heat is called an insulator.
10. The scale which shows the temperature of freezing water as $- 32$ is Fahrenheit scale.
11. The SI unit of temperature is kelvin.

Down
1. The transfer of heat energy by vibrating materials in contact with the neighbouring particles is called conduction. In solids, heat is transferred by the process of conduction.
3. A measure of the warmth or coldness of an object or substance is called temperature.
4. A colour which is a poor absorber of heat is white.
7. A material that easily allows heat transfer is called conductor.
