Question

D. Define the following.
1. Melting point
3. Deposition
2. Specific latent heat of vaporization
4. Latent heat​

Answer 1

Answer:

1. Melting point : the temperature at which a given solid will melt.

2.Specific latent heat of vaporization: the specific latent heat, either of fusion or vaporisation. As you heat a liquid such as water, and put a lot of energy into it some of the molecules will change from liquid to gas.

3.Deposition :

Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. ... One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.

4.Latent heat : Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature.

Answer 2

Answer:

1.the temperatureat which a given solid will melt.

3.it is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure.

4.the heat required to convert a solid into a liquid or vapour or a liquid into a vapour without change of temperature.
