# What has more kinetic energy hot or hot water?

## What has more kinetic energy hot or hot water?

Energy of an object equals the sum of its rest mass and the kinetic energy. The hot and cold water with same amount of molecules have same rest mass, but kinetic energy of hot water is bigger because hot water molecules are moving faster than cold water molecules.

## Which has more energy a hot cup of tea or a swimming pool?

A swimming pool at 30°C is at a lower temperature than a cup of tea at 80°C. But the swimming pool contains more water, so it stores more internal energy than the cup of tea.

## Which has more kinetic energy a cup of boiling water or a pool of cold water?

The cup with hot boiling water has more thermal energy than the cup with freezing cold water because the molecules are moving faster, which equals MORE total kinetic energy.

## Which is likely to have more kinetic energy a molecule of water in your glass of iced tea or a molecule of water in the hot shower you take every morning can you say for sure which molecule has more kinetic energy explain?

Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The water molecules in a cup of hot coffee have a higher average kinetic energy than the water molecules in a cup of iced tea, which also means they are moving at a higher velocity.

## Does hot water have more kinetic energy?

Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water. The temperature of a substance is the average* amount of kinetic energy its molecules have.

## What happens to average kinetic energy when heated?

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

## Why does a swimming pool have more thermal energy than a glass of water?

However, the swimming pool contains a lot more water. Therefore, the pool has more thermal energy than the cup of tea even though the tea is hotter than the water in the pool. This is because the large beaker contains more water and needs more heat energy to reach 100°C.

## Why does a swimming pool have more thermal energy than boiling water?

You could argue that there is much more heat in a swimming pool than in a boiling pot of water. This is because you need much more energy to raise the temperature of the swimming pool by one degree celsius than to bring the pot of water to a boil. Heat is a measure of energy.

## Does hot water or cold water have more energy?

Molecules in a liquid have enough energy to move around and pass each other. Warm water has more energy than cold water, which means that molecules in warm water move faster than molecules in cold water.

## Does the hotter block have more energy inside?

Hotter objects have a higher average kinetic energy and a higher temperature; cooler objects have a lower average kinetic energy and a lower temperature. The atoms, molecules, and ions in objects have a range of speeds and kinetic energies: some are moving faster and others are moving slower.

## Does kinetic energy decrease with temperature?

Since kinetic energy is one of the forms of internal energy, the release of heat from an object causes a decrease in the average kinetic energy of its particles. This means that the particles move more sluggishly and the temperature of the object decreases.

## Which has more heat coffee or swimming pool?

If we have a swimming pool at 35 deg Celsius, and a cup of coffee at 80 deg Celsius, the pool has more thermal energy. This is because there is much more water in the pool than the coffee.

## Does a lake have more thermal energy than a cup of coffee?

There is far more energy in a cold lake than in a cup of hot coffee, just because there is far more water in the lake.

## Why large glass of water have more heat energy than small one?

You will notice that will take longer to boil the water in the large beaker than the water in the small beaker. This is because the large beaker contains more water and needs more heat energy to reach 100°C.
