Question

Name the following:
1.The angle between incident ray and normal.
2. The Sl unit of heat
3.The process of changing from liquid state to gaseous state at a constant temperature
4. The temperature of pure melting ice.​

Answer 1

Answer :-

1) The angle between incident ray and normal is called angle of incidence.

2) SI unit of heat is joule.

As heat is a form of energy, the SI unit of heat will be same as that of energy.

3) The process of changing from liquid state to gaseous state at a constant temperature evaporation.

4) The temperature of pure melting ice is 0°C

Answer 2

Answer:

1. angle of reflection
2. joule
3. evaporation
4. 32°F
