How much heat is required to heat 3kg water by 40 degrees?
| September 4, 2021 | education
m = 3 kg.
C = 4200 J / kg * ° C.
Δt = 40 ° C.
Q -?
The amount of heat Q required for heating water is determined by the formula: Q = C * m * Δt, where m is the mass of heated water, C is the specific heat capacity of water, Δt is the change in water temperature.
Q = 3 kg * 4200 J / kg * ° C * 40 ° C = 504000 J.
Answer: to heat water, you need Q = 504000 J of thermal energy.
