GC Thermochemistry Review

Front

What happens along the BC line in a heating curve?

Back

Boiling/Condensing.

Front

Which line segment represents an increase in potential energy and no change in average kinetic energy?

Back

Line segment BC.

Front

What does the law of conservation of energy state?

Back

In any chemical or physical change, energy cannot be created or destroyed, only changed in form.

Front

What is the capacity to do work or supply heat?

Back

Energy.

Front

What type of process occurs when heat flows from the system to the surroundings?

Back

Exothermic process.

Front

What is thermochemistry?

Back

The study of heat changes that occur during chemical reactions and physical changes.

Front

Define specific heat capacity.

Back

The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is an endothermic process?

Back

A process that absorbs heat from the surroundings.

Front

What is an exothermic reaction?

Back

A reaction that releases heat to the surroundings.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.
