Answer 2

Answers are Joule and Latent heat.

Correct options are (A) and (D).

Explanation:

Heat is a form of energy. Its unit is Joule.

(a) Joule (b) Centigrade (c) Reaumer (d) Kelvin

Joule is defined as:

When a force is applied on an object, then it moves a distance of one meter in the direction of force is known as work done which is equal to one joule. It is S.I unit of work or energy.

2. Calorimeter is a device by which we can measure :

(a) heat

(b) temperature

(c) specific heat

(d) latent heat

Latent heat is defined as "It is the amount of heat required to convert a solid into a liquid or vapour, or a liquid into a vapour state without changing the temperature."
