Answer:
Q = 292.6 kJ
Explanation:
First, let's make sure all the values are in appropriate units.
C (specific heat of water) = 4.18 J/g °C
m (mass of water) = 2000 g
∆T = 35 °C
The equation for the needed amount of energy is:
Q = m • C • ∆T
So, we simply multiply the given values:
Q = 2000 • 4.18 • 35
Q = 292600 J
If we want the answer in kilojoules (kJ), we simply divide the value in joules with 1000:
Q = 292600 / 1000 = 292.6 kJ
I hope this helps.
