How do you calculate the mass of a substance given heat energy, specific heat, and temperature change?

Back

Mass = Heat Energy / (Specific Heat × Temperature Change). For example, for iron: Mass = 50 J / (0.10 J/g°C × 25.0°C) = 20g.

What is the term for the change from a liquid to a gas?

Back

Vaporization.

What happens when two objects at different temperatures come into contact?

Back

Heat flows from the warmer object to the cooler one until they both have an equal temperature.

What does it mean when a substance is described as 'evaporating'?

Back

It is transitioning from a liquid state to a gas state.

Front

Define specific heat capacity.

Back

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

Front

What is the formula for calculating heat energy?

Back

Heat Energy = Mass × Specific Heat × Temperature Change.

Front

What is condensation?

Back

Condensation is the process by which a gas turns into a liquid.

Front

What is sublimation?

Back

Sublimation is the transition of a substance directly from solid to gas without passing through the liquid state.

Front

What is deposition?

Back

Deposition is the process where a gas transforms directly into a solid without becoming a liquid first.
