HONORS Heating Curve Graphs

Front

What is a heating curve?

Back

A heating curve is a graphical representation of the temperature change of a substance as it is heated over time, showing phase changes and temperature changes.

Front

What happens at the plateaus of a heating curve?

Back

At the plateaus, the temperature remains constant as the substance undergoes a phase change (e.g., solid to liquid or liquid to gas).

Front

What is the boiling point of a substance?

Back

The boiling point is the temperature at which a substance changes from a liquid to a gas.

Front

What is the condensation point of a substance?

Back

The condensation point is the temperature at which a substance changes from a gas to a liquid.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which increases as temperature increases.

Front

What happens to kinetic energy during a phase change?

Back

During a phase change, the kinetic energy remains constant while the potential energy changes.

Front

What is the specific heat capacity of a substance?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the formula to calculate heat absorbed or released?

Back

The formula is: Q = m * C * ΔT, where Q is heat, m is mass, C is specific heat capacity, and ΔT is the change in temperature.

Front

What is the heat of fusion?

Back

The heat of fusion is the amount of heat required to convert a unit mass of a solid into a liquid at its melting point.

Front

What is the heat of vaporization?

Back

The heat of vaporization is the amount of heat required to convert a unit mass of a liquid into a gas at its boiling point.
