Transfer of Energy & Specific Heat Regents Practice

Front

What is the method of energy transfer primarily responsible for energy being lost from Earth into space?

Back

Radiation

Front

How does heat flow?

Back

Always from warm to cold.

Front

What happens to the temperature of a substance when heat is released?

Back

It decreases.

Front

What is the basic difference between ultraviolet, visible, and infrared radiation?

Back

Wavelength.

Front

Identify the types of heat transfer at A, B, and C: A-Conduction, B-Convection, C-Radiation.

Back

A-Conduction, B-Convection, C-Radiation.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat by the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves.

Front

What is specific heat?

Back

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

Front

What is the formula for calculating heat energy?

Back

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