Answer 29

Thermal Expansion

Question 30

An apparatus for measuring the amount of heart involved in a chemical reaction or other process

Answer 30

Calorimeter

Question 31

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Answer 31

Convection

Question 32

the emission of energy as electromagnetic waves or as moving subatomic particles, esp. high-energy particles that cause ionization.

Answer 32

Radiation

Question 33

The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container.

Answer 33

Kinetic molecular theory
