Calculations with Heat Changes

Mathematical processes used to determine the changes in thermal energy, often requiring formulas related to mass, specific heat, and temperature change. Key formulas include:
1. **Q = mcΔT**: where Q is the heat energy absorbed or released, m is the mass, c is the specific heat, and ΔT is the change in temperature.
2. **Q = mL**: for phase changes, where L is the latent heat (such as enthalpy of fusion or vaporization). Understanding these concepts is crucial for calculating energy transfer in thermal processes.

Specific Heat

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Steam

Water in the form of vapor when it is heated above its boiling point.

Ice

Frozen water, a solid state of the substance formed at 0 degrees Celsius or below.

Thermal Energy Transfer

The process of heat transferring from one substance to another, typically occurring during phase changes.

Mass of Ice Left

The amount of ice that remains after a heating or cooling process, often considered in heat transfer calculations.

Calculations with Heat Changes

Mathematical processes used to determine the changes in thermal energy, often requiring formulas related to mass, specific heat, and temperature change.

Equilibrium Temperature

The final temperature attained when two substances of different temperatures reach a state of balance.

Temperature Change

The difference in temperature of a substance before and after a phase change or thermal process.

Enthalpy of Fusion (mL)

The heat required to change a unit mass of a solid into a liquid at constant temperature.
