What is the latent heat of fusion

It is the amount of heat that is required to melt something, and the amount of heat that it gives off when it freezes. (They are the same amount.)

What most determines the entropy of a solid

The crystalline structure of the solid most determine the entropy of a solid.

How does entropy change in gas reactions

Reactions that increase the moles of gas will increase in entropy.

Which equation shows how frequency is related to velocity and wavelength

F=v/&

What chemical reaction describes where energy is absorbed

You think probable to an endothermic chemical reaction.

How much energy is released when 6 g of water is condensed from water vapor

6.212

A rocket uses an engine that creates thrust through the combustion of a liquid fuel and an oxidizer. What kind of rocket is this

Chemical rocket


What does the second law of thermodynamics say apex

The entropy of the universe is increasing

Which of the following is the best thermal insulator APEX

Air

(Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).
