Thermo-Energy Unit Review

Front

What is Specific Heat?

Back

The amount of energy required to raise the temperature of 1 kilogram of a substance by 1ºC.

Front

How do you calculate Specific Heat Capacity?

Back

Specific Heat Capacity = Heat Energy (J) / (Mass (g) × Temperature Change (ºC))

Front

What is the Critical Point in thermodynamics?

Back

The temperature and pressure at which the distinction between liquid and gas phases disappears.

Front

How much heat is needed to raise the temperature of 200 grams of water from 15.0ºC to 100.0ºC?

Back

34 kJ

Front

What does a Cooling Curve represent?

Back

A graph showing the change in temperature of a substance as it cools and changes phase.

Front

What is Thermal Energy?

Back

The total kinetic energy of particles in a substance, related to temperature.

Front

Define Temperature in the context of thermodynamics.

Back

A measure of the average kinetic energy of the particles in a substance.

Front

What is the formula for calculating heat energy?

Back

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

Front

What is the difference between Kinetic Energy and Thermal Energy?

Back

Kinetic Energy is the energy of motion, while Thermal Energy is the total energy of all particles in a substance.

Front

What is the Normal Melting Point?

Back

The temperature at which a solid becomes a liquid at standard atmospheric pressure.
