Water Heating Calculator for Time, Energy, and Power
it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62. But when the state of water changes from solid to fluid (e.g. -2°C to + 2°C) or from fluid to gas (e.g. 98°C to 102°C) this does not hold true any more. It would be more complicated to build calculators that can ...

Specific Heat Calculator
The specific heat of aluminum is 897 J/kg K. This value is almost 2.3 times of the specific heat of copper. You can use this value to estimate the energy required to heat a 500 g of aluminum by 5 °C, i.e., Q = m × Cp × ΔT = 0.5 × 897 × 5 = 2242.5 J.
How Long Does It Take To Heat a Pool?
The results would be 1.20 x 3.36 x 9.91, or $39.95 to heat your pool initially. As you may imagine, it costs a lot less to keep a pool warm than it does to heat it from a colder temperature. The exact cost will again depend on environmental variables, how many gallons are your pool, and your desired temperature.

5.2 Specific Heat Capacity
Heat Capacity . The heat capacity of a substance is defined as the amount of heat it takes to raise the temperature of a substance by 1°C. In equation form, this can be represented as the following: or . Note: You can determine the above equation from the units of Capacity (energy/temperature).
How do you calculate the energy needed to heat water?
The equation for the amount of thermal energy needed to produce a certain temperature change is as follows: #q = cmDeltaT# Where: #q# is the amount of thermal energy #c# is the heat capacity of water (#~~ 4.184 J/g^oC#) #DeltaT# is the change in temperature.
