Physics 2005 JAMB Past Questions - Question 45: 10j of heat is required to boil of completely 2kg of a certain liquid neglecting heat loss to the surrounding the latent heat of vapourisation of the liquid is

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.
