Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
A
Explanation
To find the latent heat of vaporization of the liquid, you can use the formula:
Latent Heat of Vaporization (L) = Heat Energy (Q) / Mass (m)
In this case, the heat energy required to completely boil 2 kg of the liquid is 10^6 J, and the mass (m) is 2 kg.
L = 10^6 J / 2 kg
L = 500,000 J/kg
So, the latent heat of vaporization of the liquid is 500,000 J/kg.
