Specific Heat Capacity and Thermal Reactions

Vocabulary terms and definitions covering the specific heat capacity formula, temperature change variables, and reaction types from the lecture.

$$q$$

The symbol representing joules (energy) in the specific heat formula.

$$m$$

The mass in the formula $q = mc\triangle T$.

$$c$$

The specific heat capacity in the formula $q = mc\triangle T$.

$$\Delta$$

A mathematical symbol meaning change.

$$\Delta T$$

The change in temperature, calculated as $T_f - T_i$.

Change in temperature

The value obtained by subtracting the initial temperature from the final temperature ($T_f - T_i$).

Exothermic

Identified in the lecture as occurring when heat is absorbed and it is negative.

Endothermic

Identified in the lecture as occurring when heat is released and it is positive.
