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.
Who created the model of the atom that has quantizied levels of energy
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
1/2 N2(g) + O2(g) + 33.1 kJ NO2(g)
What is a correct description of the enthalpy of a reaction
The enthalpy of a reaction does not depend on the intermediate reactions.
What does S0 mean
the system has become more random
If you need to reverse the following reaction in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this in
