Thermo review c1

Front

What is the final temperature when mixing two cups of water at different temperatures?

Back

The final temperature will be between 50°C and 100°C.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What happens to the temperature of a glass of cold water over time?

Back

It will eventually match the temperature of the surrounding environment.

Front

What is a closed system in energy conservation?

Back

A closed system exchanges energy but not matter with its surroundings.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat energy by electromagnetic waves.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects reach the same temperature and no heat flows between them.

Front

What is the specific heat capacity?

Back

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

Front

What is the formula for calculating heat transfer?

Back

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