AP®︎ Chemistry: Topic 6.4 Flashcards

The measurement of heat transfer by tracking temperature changes in an insulated system.

q = mcΔT, where heat equals mass times specific heat times temperature change.

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

Heat capacity is heat per degree for an object; molar heat capacity is heat per degree per mole.

The difference between final and initial temperature, calculated as Tfinal minus Tinitial.

Energy is conserved; it can be transferred or converted but not created or destroyed.

In an isolated calorimeter, energy released by one part equals energy absorbed by another.

Positive q means heat is absorbed; negative q means heat is released.

For equal heat and mass, a larger specific heat gives a smaller temperature change.

Set heat lost equal to heat gained, then solve q = mcΔT for c.

Systems change energy through heating or cooling, phase changes, and chemical reactions.

An insulated constant-pressure setup where measured heat equals the reaction’s enthalpy change.

A calorimetry method using solution temperature changes to identify heat flow during dissolving.

The state reached when objects in contact stop changing temperature.
