Common questions
What is the Heat Capacity formula?
Heat Capacity is written Q = mcΔT. Heat required to change temperature of a substance. It belongs to Thermodynamics, under Heat & Temperature.
What are the units in Q = mcΔT?
In SI units, Q is heat, measured in kg·m²/s²; m is mass, measured in kg; c is specific heat, measured in m²/(s²·K); ΔT is temperature change, measured in K.
How is the Heat Capacity formula derived?
Q = mcΔT by definition of specific heat capacity. The result is Q = mcΔT.
