A certain amount of heat is added to 1 cup of water and the temperature raises by 5°C. How much will the temperature raise if three times the amount of heat is added to the same amount of water?

Rise in temperature is 15°C.

Explanation:

We know that

Q = m c ΔT

Q - heat required

m - mass of the substance

c - specific heat capacity

ΔT - change in temperature

Given :

1 cup of water = 250 mL =250 g

specific heat capacity of water = 4.184 J/g°C

temperature rises by 5°C

If three times of heat is added

Therefore

Rise in temperature is 15°C.
