Question

What name is given to heat transfer process in liquid and gaseous matters?

Answer 1

The process of heat transfer in liquid and gaseous matters is Convection.

Explanation:

It is a mode of heat transfer in which molecules of substance physically move from one place to another for heat transfer. Hence, warmer areas of gas and liquid travel towards the cooler areas of gas and liquid.

It can also be technically termed as the heat transfer due to the bulk motion of fluid molecules in a gas or liquid.

Answer 2

The name that is given to the heat transfer process in liquid and gaseous matters is 'convection'.

Explanation:

• There are various processes through which heat can be transferred from one substance to another.

• Some of these processes are named as conduction, convection, radiation, etc.

• In liquids and gases, when the substance layer with warmer temperature rises to replace the substance layer having a lower temperature, 'convection' is said to have occurred.

• In this process, the lighter matter moves upwards and the heavier one moves downwards.

• When the lighter matter is exposed to the surface, it loses heat and gets heavier to match with the underlying matter.
