(b) The amount of heat required to raise the temperature of a substance is called its specific heat capacity.

(c) The process of heat transfer in liquids and gases is through convection mode.

(d) The process of heat transfer from a body at higher temperature to a body at lower temperature without heating the space between them is known as radiation.

Answer 1

(b) The amount of heat required to raise the temperature of a substance is called its specific heat capacity.

The amount of heat required to raise the temperature of a substance is called its specific heat capacity is not correct statement, because specific heat capacity represents the amount of heat required to raise the temperature of 1 kg of a body by 1°C.
