The mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.
How to calculate mass?
The mass of a substance can be calculated by using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
22000 = m × 4.2 × (100 - 34)
22000 = 277.2m
m = 22000/277.2
m = 79.37g
Therefore, the mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.
