Question

What would happen to a 10 kg block of ice if you slowly increased the kinetic energy of the molecules within the ice? A) The ice would melt. B) Sublimation would occur. C) The ice would remain frozen. D) Water vapor near the ice would also freeze.

Answer 1

i believe its A)the ice would melt, since It would then warm up until eventually it would reach the freezing/melting point (same thing). At that point, as you add more heat, the energy would go into breaking the hydrogen bonds holding the solid structure together instead of raising the temperature (kinetic energy)

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

It is known that in solids, molecules are held together by strong intermolecular forces of attraction. As a result, these molecules are unable to move from their initial position unless and until the molecules don't gain kinetic energy.

Hence, when molecules of a 10 kg block of ice gains kinetic energy then its molecules tend to move from their initial position. Hence, more number of collisions take place between them.

As a result, change in state occurs from solid to liquid.

Thus, we can conclude that for a 10 kg block of ice if you slowly increased the kinetic energy of the molecules within the ice then the ice would melt.
