What is the Thermal Energy Formula? (thermal energy formula, thermal energy equation)
The thermal energy formula is used to calculate the amount of heat energy transferred or stored in a system. It is expressed as:
Q = mcΔT
Where:
- Q = Heat energy (in joules, J)
- m = Mass of the substance (in kilograms, kg)
- c = Specific heat capacity (in joules per kilogram per degree Celsius, J/kg°C)
- ΔT = Change in temperature (in degrees Celsius, °C)
This formula is fundamental in fields like physics, engineering, and environmental science, enabling precise energy calculations. (thermal energy calculations, heat energy formula)
How to Use the Thermal Energy Formula (thermal energy calculations, heat transfer formula)
Follow these steps to apply the thermal energy formula effectively:
