To find the amount of heat needed to warm the water, you can use the formula:
Q = mcΔT
where Q is the heat energy required, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the temperature change.
The specific heat capacity of water is 4.18 J/g°C.
Plugging in the given values, you get:
Q = 24.6 kg * 4.18 J/g°C * (60.0°C - 20.0°C) = 24.6 kg * 4.18 J/g°C * 40.0°C = 5052.8 J
So the amount of heat needed to warm the water from 20.0°C to 60.0°C is approximately 5052.8 J.
