To calculate the energy required to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q = energy (in joules)
m = mass of the substance (in kilograms)
c = specific heat capacity of the substance (in joules per kilogram per degree Celsius)
ΔT = change in temperature (in degrees Celsius)
First, let's calculate the change in temperature:
ΔT = final temperature - initial temperature
= 80°C - 45°C
= 35°C
Next, we need to find the specific heat capacity of water, which is approximately 4,186 joules per kilogram per degree Celsius.
Now, we can substitute the values into the formula:
Q = 50 kg * 4,186 J/kg°C * 35°C
= 734,150 joules
Therefore, it would require approximately 734,150 joules of energy to raise 50 kg of warm water from 45°C to 80°C.
