How much water can be heated to 60 degrees, giving it 504 kJ?
| December 5, 2020 | education
The amount of heat is found by the formula Q = c * m * Δt, where c is the specific heat capacity (tabular value), m is the mass, Δt is the temperature change during heating. Let’s express the mass.
m = Q / (s * Δt)
s = 4200 J / kg ° C
Let’s translate the amount of heat into the SI system:
504 kJ = 504 000 J
m = 504,000 / (4200 * 60) = 2 kg
Answer: 2 kg
