How to calculate
Estimate heat added or removed when a material changes temperature using its mass and specific heat, keeping the sign of the temperature change.
Heat energy = m*c*t J; Heat energy = m*c*t/1000 kJ
Worked example
Mass (kg): 1; Specific heat (J/kg·K): 4184; Temperature change (K): 20.
Heat energy: 83,680 J; Heat energy: 83.68 kJ.
Assumptions and limits
Estimate heat added or removed when a material changes temperature using its mass and specific heat, keeping the sign of the temperature change. Constant specific heat without phase changes. Positive temperature change adds heat; negative change removes heat. A kelvin difference equals a Celsius difference.
