In a thermos flask, the silvered walls reflect and radiate the heat outside- False.
Correct statement:
In a thermos flask, the silvered walls reflect radiated heat back to the liquid in the bottle.

The amount of heat gained by a substance is equal to the product of its mass and latent heat- True.

Convection is the process by which the thermal energy flows in solids- False.
Correct statement:
Convection is the process by which thermal energy flows in liquids and gases.

The process of converting a substance from a solid state to gaseous state is called condensation- False.
Correct statement:
The process of converting a substance from solid to gas is called sublimation.

The dimensions of a substance are increased if the temperature of the substance is decreased- False.
Correct statement:
The dimensions of a substance are increased if the temperature of the substance is increased.

The applied heat energy can be realised as an increase in the average kinetic energy of the molecules- True.
