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 •

Which phase has the highest entropy

Gas

A cat with two kittens are sleeping or A cat with two kittens is sleeping.

'with two kittens' describe the cat. So, you should write 'is sleeping'. But if you mean that all three of them are sleeping, write 'A cat and his two kittens are sleeping'.

What does it mean for heat to be transferred by radiation

Energy is transferred when molecules absorb electromagnetic waves.

How does temperature affect the spontaneity of a reaction

if H and S have the same sign the temperature will determine spontaneity

What does it mean for heat to be transferred by convection

Energy is transferred through moving currents of warmer air or liquid.

How does the ocean affect coastal climate

the specific heat keeps the ocean temperatures more even

What does the latent heat of vaporization represent

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

What would cause entropy to decrease in a reaction

The products becoming more ordered than the reactants

What information does Gibbs free energy give about a reaction

It tells if the reaction will process spontaneously or not

How is stoichiometry used to calculate energy released when a mass of liquid freezes

Grams liquid × mol/g × Hfusion

What is the value for G at 300 K if H 27 kJmol and S 0.09 kJmolK

G = 0 kJ/mol

What phase has the lowest entropy

solid-apex

What is the value for triangle G at 1000 K if triangle H -220 kJmol and triangle S -0.05 kJ(mol.K)

-170kJ

What can be said about a reaction with triangle H 620 kJmol and triangle S -046 kJ(mol.K)

it is never spontaneous

What statement best describes the second law of thermodynamics

How energy changes or moves

What volume of water can be boiled by 3 kJ of energy

1.3 ml
