Kinetic Theory and the Phases

Front

What is the amount of energy required to raise the temperature 1ºC for every gram called?

Back

Specific Heat

Front

What happens to gas pressure when temperature increases, more gas is added, or volume decreases?

Back

Gas pressure increases.

Front

Which cup has the least thermal energy if all are at the same temperature?

Back

The small cup (Tall) has the least thermal energy.

Front

What is the specific heat of aluminum?

Back

0.21 cal/g° C

Front

How much heat (Q) is released when a 10 g piece of aluminum cools from 100° to 50°?

Back

105 J

Front

What occurs when a hot metal sample is dropped into room temperature water?

Back

The heat from the metal travels into the water.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

Explain the relationship between temperature and kinetic energy.

Back

As temperature increases, the kinetic energy of particles increases.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is heat, m is mass, c is specific heat, and ΔT is the change in temperature.
