Question

The same amount of heat is removed from 2kg of water and from 1kg of water starting at the same temperature. What happen?

Answer 1

The temperature of the 1 kg water will be lower.
Q=mcΔt
Q1= 1kg*c*Δt(1)
Q2= 2kg*c*Δt(2)

Q1=Q2
 1kg*c*Δt(1) = 2kg*c*Δt(2)
 Δt(1) = 2Δt(2)
We can see that change in temperature for 1 kg will be 2 times more that change in temperature for 2 kg of water.

Answer 2

The temperature of the 1kg will boil faster than the 2kg.
Because of the Specific Heat capacity.
