Chapter 10 (Thermal properties of matter)

Question 1

What is internal energy

Answer 1

An energy store that is made up of the total kinetic energy associated with the random motion of the particles and the total potential energy between the particles in the system

Question 2

What factors affect heat capacity

Answer 2

• the number of particles
  (more particles->more energy to be stored->larger heat capacities)
  -strength of intermolecular forces
  (stronger intermolecular forces->larger heat capacities)

Question 3

What is heat capacity

Answer 3

Is the change of its internal energy per unit change in its temperature

Question 4

How to find heat capacity

Answer 4

C= change in internal energy by energy transfer/change in temperature
