Question

what is used to measure heat?
change in temperature
constant temperature
constant specific heat
change in specific heat

Explanation:

Heat is measured using the formula \(Q = mc\Delta T\), where \(Q\) is heat, \(m\) is mass, \(c\) is specific heat capacity (constant for a given substance under certain conditions), and \(\Delta T\) is the change in temperature. So, the change in temperature (\(\Delta T\)) is used in the calculation to measure heat. Constant temperature would mean \(\Delta T = 0\) and no heat transfer (from that temperature - change aspect) if other factors are constant. Specific heat (\(c\)) is a property of a substance and its change is not directly what is used to measure heat in the basic heat - transfer formula \(Q = mc\Delta T\).

Answer:

change in temperature
