What happens to water at 0 C?
It moves through conduction, because heat is transferred directly from the hot chocolate to the spoon.
No change in energy absorption and a phase change
liquid
Water has a higher specific heat and so required more energy to change its phase
The convection of water currents as warm water rises and cool water sinks
The particles in the rod move faster when heated, which causes the wax to get hot and melt
Solid water is being converted from a solid to a liquid by absorbing heat energy from the surroundings
The molecular motion will increase as more thermal energy is absorbed
What is happening when a substance is boiling?
It moves through conduction, because heat is transferred directly from the hot chocolate to the spoon.

During an experiment, black pepper was added to water as it boiled strongly, and the pepper moved in a circular pattern from the top of the water to the bottom and back again. What does the circular pattern of the pepper represent?
It moves through conduction, because heat is transferred directly from the hot chocolate to the spoon.
