Question

What is the melting point of a substance?

(a) The temperature at which a liquid melts

(b) The temperature at which a gas will completely boil away

(c) The temperature at which the solid state turns into a liquid state

Answer 1

The correct answer should be C. The temperature at which the solid state turns into a liquid state.
A doesn’t make sense (a solid needs to melt, not a liquid)
B is evaporation I would think.
