What is thermal energy

The total kinetic energy of the particles in a system

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 defines an exothermic reaction

A reaction that produces heat

What does the latent heat of vaporization represent

The amount of energy required to turn a mole of a liquid into a gas

How does entropy change in gas reactions

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

How much energy is generated from freezing 2.5 g water

2.5 g 1 mol/18.02 g (-285.83) kJ/mol

Which term below describes the study of how energy is transferred to different locations and forms

thermodynamics

Which of the following would have the best thermal conductor properties

A cup made of metal. (Apex)

How can one tell if a reaction has reached its equilibrium

All motion ceases

Which question would best help a writer choose evidence to support a claim

Does this evidence support what I am trying to say

What is the purpose of the flame that is lit below a hot air ballon

That flame is the source of heat for the hot air in the hot air balloon.

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).
