We calculate heat using the equation q = (m)(c)(∆T). If we have 50.0 g of water, how much heat do we need to raise the temperature by 20℃ if the specific heat of water (c) is 4.2 J/g℃ ?

Answer:
To calculate the energy required to raise the temperature of any given substance, here's what you require:
The mass of the material, m.
The temperature change that occurs, ΔT.
The specific heat capacity of the material, c (which you can look up). ...
Here is a source of values of c for different substances:
Q=m×c×ΔT.

Answer:
q=4200 J
Explanation:
q=mcΔt. as m=50g,c=4.2 j/g °c, Δt=20 °c, so q= 50×4.2×20 =4200 J
