Q1: What do you see in the liquid when it boils?

[Answer]

When a liquid is heated a lot it changes into a gas quickly. This is called boiling.

When something boils, the liquid particles shake themselves apart so violently that they come free inside the liquid, not just on the surface (which is what happens in evaporation). When the particles shake free they become a gas and we see this as bubbles inside the liquid.
