Thermochemistry Review

Front

What is specific heat?

Back

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

Front

Name a substance that has a HIGH specific heat value.

Back

Water.

Front

If the reaction is endothermic, how does heat flow?

Back

Heat flows from the surrounding to the system.

Front

Which substance will take the LONGEST to heat up based on specific heat values?

Back

Milk: 3.89 J/gC.

Front

Calculate the specific heat of a piece of wood if 1500 grams of wood absorbs 6750 J of heat and its temperature changes from 32C to 57C.

Back

0.18 J/gC.

Front

Heat will always flow from a ______ object to a ______ object.

Back

Warm to Cold.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What is the formula for calculating heat (q)?

Back

q = m * c * ΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What does ΔT represent in thermochemistry?

Back

ΔT represents the change in temperature, calculated as final temperature minus initial temperature.
