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 definition of specific heat

The heat needed to raise the temperature of 1 g of a substance 1° C - apex

What happens to a substances temperature during a phase change

The temperature either increases or decreases which causes the different phase changes

Why does a cold pan heat up when it is placed on a hot stove

Because the pan and the stove is the same temp. and when the stove is heated it transfers through the pan and makes the pan hot.

How does entropy change in gas reactions

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

Which of the following reactions shows that the formation of NO2 requires 33.1 kJ mol
