## What happens to the molecules of water in the container when the temperature increases?

An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.

What happens to the molecules when heated?

Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid. However, gases that are contained in a fixed volume cannot expand – and so increases in temperature result in increases in pressure.

What happened to the food coloring in the hot water?

In hot water, the food coloring diffuses (spreads out) through the water quickly. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster.

### What will happen to the dissolving rate of sugar if hot water was added to the juice Why?

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster.

What happens to the molecules of water in the container?

The liquid molecules escape into the gas phase, becoming water vapor. Vaporization is the process in which a liquid is converted to a gas. If the water is instead kept in a closed container, the water vapor molecules do not have a chance to escape into the surroundings and so the water level does not change.

What happens to molecules when the temperature drops or lowers?

As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down. If a liquid is cooled sufficiently, it forms a solid.

## What happens to the hot water and a drop of food coloring after 5 minutes?

The food coloring you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the food coloring spreads out quicker in the warm water than in the cold water.

Why do molecules move faster in hot water?

What’s happening in there? Heat is a form of energy. The heat energy from the water makes the water molecules in the hot water move faster than the water molecules in the cold water.

What happens when you put sugar in boiling water?

The addition of sugar to boiling water forms a paste, which sticks to skin and intensifies burns. It is a tactic commonly used in prisons, where it is described as “napalm” due to the way it attaches to skin and burns.

### What will be the most effective means of increasing the dissolving rate of sugar in water answer?

Answer: The effective means of increasing the dissolving rate of sugar in water is by stirring or agitating the solution. The stirring allows fresh solvent molecules to continually be in contact with the solute. Hot water dissolves faster than cold water.
