What is thermodynamics

the study of the movement of energy and heat.

or

Thermodynamics is the branch of physics concerned with the conversion of different energy forms.

•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •

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.)

Is plastic a thermal conductor or insulator

It is a thermal insulator

What defines an exothermic reaction

A reaction that produces heat

How does the phase of water affect its specific heat capacity

Liquid water has the highest specific heat capacity.

What equation represents the energy it takes to heat a substance

Q=mc∆T

What is the energy required to go from liquid to gas called

The latent heat of vaporization

What does the field of thermodynamics relate to

Changes in energy in systems

What does it mean if Keq is less than 1

Reactants are favored over products in the reaction.

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).
