Matter around us 2 short Flashcards
1
Q
What are fluids?
A
The states of matter that can flow due to less intermolecular force of attraction, like liquids and gases are called fluids.
2
Q
Define latent heat of vaporization.
A
Latent heat of vaporization is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point.
3
Q
Define latent heat of fusion.
A
Latent heat of fusion is the amount of heat energy required to change 1 kg of solid into liquid at its melting point.
4
Q
Define sublimation.
A
Sublimation is the change of a solid-state directly to a gaseous state without going through a liquid state.
5
Q
What is dry ice?
A
Solid carbon dioxide is obtained by cooling and applying pressure on carbon dioxide gas. It does not melt so it is called dry ice.
