| How much heat will be released during the condensation of water weighing 400 g? The specific heat of vaporization of water is 2.3 * 10 to the sixth power J / kg.
Condition:
m = 400 g = 0.4 kg.
L = 2.3 * 10 ^ 6 J / kg.
To find :
Q-? J.
Decision :
Q = L * m.
[Q] = J / kg / kg = J * kg / kg = J.
Q = 2.3 * 10 ^ 6 * 0.4 = 920000 (J).
Answer: 920000 J = 920 kJ.
