Define specific heat at constant volume
WebOct 5, 2024 · 2. If a body absorbs a quantity of heat q its temperature will normally rise by a value Δ T. The average heat capacity over this temperature range is defined as C a v ≡ q / Δ T. The instantaneous heat capacity at temperature T is C ≡ d q / d T. This definition is not exact enough, however, until the path of heating is specified. WebThere are two main ways that heat capacity is reported. The specific heat capacity (also called specific heat), represented by the symbol c \text c c start text, c, end text or C …
