Flashcard Calorimetry

Front

What happens when two objects with different temperatures come in contact?

Back

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

Front

What is the specific heat of a substance?

Back

The amount of thermal energy required to raise the temperature of one (1) gram of a substance by 1°C.

Front

How can you determine if a reaction is exothermic or endothermic?

Back

If the temperature of the reaction increases, it is exothermic; if it decreases, it is endothermic.

Front

What does a high specific heat indicate about a substance?

Back

It requires a lot of energy to become hot.

Front

What is true about an endothermic reaction?

Back

It absorbs heat from the surroundings.

Front

What is calorimetry?

Back

The science of measuring the heat of chemical reactions or physical changes.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact no longer transfer heat, as they have reached the same temperature.

Front

What is the heat of fusion?

Back

The amount of energy required to change a substance from solid to liquid at its melting point.

Front

What is the heat of vaporization?

Back

The amount of energy required to change a substance from liquid to gas at its boiling point.

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings.
