Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
D
Explanation
Latent heat of vaporization = Heat energy / Mass
Given that 10^6 J of heat is required to boil off completely 2 kg of the liquid, we can substitute these values into the formula:
Latent heat of vaporization = 10^6 J / 2 kg
Calculating this, we get:
Latent heat of vaporization = 500,000 J/kg
Therefore, the latent heat of vaporization of the liquid is 500,000 J/kg.
