The energy gained by water is an important concept in thermodynamics and heat transfer. It refers to the amount of heat energy absorbed by water when it is heated. This energy depends on the mass of the water, its specific heat capacity, and the change in temperature.
Formula
The formula to calculate the energy gained by water is:
Q=m⋅c⋅ΔTQ = m \cdot c \cdot \Delta TQ=m⋅c⋅ΔT
where:
- QQQ is the energy gained by water (Joules)
- mmm is the mass of water (kg)
- ccc is the specific heat capacity of water (J/kg°C)
- ΔT\Delta TΔT is the change in temperature of water (°C)
How to Use
