## Why do liquids have higher specific heat capacity than solids?

In general the heat capacities of solids and liquids are higher than those of gases. This is because of the intermolecular forces operating in solids and liquids. When we heat solids and liquids, we need to supply them with potential energy as well as kinetic energy.

## Why is it that liquid water has a higher specific heat than solid water the specific heat of ice is only half the specific heat of water?

When matter is heated, the kinetic energy of its particles increase, and the intermolecular bonds are broken. Ice has a covalent molecular structure, which make its intermolecular bonds easier to break than that of water. Therefore, the specific heat capacity of ice is lower than that of water.

Water

## Does anything have a higher specific heat than water?

On a mass basis hydrogen gas has more than three times the specific heat as water under normal laboratory conditions. Diatomic gases under ambient conditions generally have a molar specific heat of about 7cal/(mol K), and one mole of hydrogen has only 2g mass. Thus 3.5cal/(g K) for hydrogen versus 1cal/(g K) for water.

## How can you increase the heat capacity of water?

Temperature, pressure, phase all affect water at the molecular level and therefore the microscopic manner in which the water will absorb energy. So yes, the heat capacity of water can be increased/decreased by changing the macroscopic conditions (phase, temperature and pressure).

## Can liquid water be over 100 degrees?

Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). Heating water above its boiling point without boiling is called superheating. If water is superheated, it can exceed its boiling point without boiling. To experience this, put a container of bottled water into a bowl of ice.

3.993 J/(g K)

## Does salt increase the specific heat of water?

When salt is present, the heat capacity of water decreases slightly. Seawater of 35 psu has a specific heat of 0.932 compared with 1.000 for pure water. Pure water freezes at 0 °C and boils at 100 °C (212 °F) under normal pressure conditions.

## Why do we add salt to boiling water?

In fact, adding salt does the very opposite of making water boil faster. Instead, it makes it take longer for the water to boil! The salt actually increases the boiling point of the water, which is when the tendency for the water to evaporate is greater than the tendency for it to remain a liquid on a molecular level.

## Does salt water heat up faster than freshwater?

The higher the heat capacity the more slowly the water will heat, given the same amount of energy added. The heat capacity of freshwater is 4.182 J/(g K) and the heat capacity of salt water is 3.993 J/(g K). Therefore saltwater will heat up faster than freshwater.

## How can you separate salt from water?

For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container.

## Can you drink sea water if you boil it?

If you have collected water from the ocean, boil it for five minutes to kill the microscopic life in the water. Taste the salt water. It is not necessary to drink any of it.

## How can you separate salt from water without boiling?

The most common type of membrane separation is called reverse osmosis. Seawater is forced through a semipermeable membrane that separates salt from water. Because the technology typically requires less energy than thermal distillation, most new plants, like Tampa’s, now use reverse osmosis.

## Can you boil sea water to get salt?

I barely noticed any residue on the filter, even, but it probably depends on your source. Bring it to a boil and cook it until the water evaporates and you’re left with salt. Lovely, damp, fine-grained sea salt. It’s really that simple.

## Can you drink rain water?

Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Only rain that has fallen directly from the sky should be collected for drinking. It should not have touched plants or buildings. Boiling and filtering rainwater will make it even safer to drink.

## Why is drinking salt water harmful?

Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.

## Can I make my own sea salt?

If you live near a non-polluted source of salt water you can make your own sea salt—simply gather salt water in clean milk jugs or soda bottles, pour it into a large pot through cheesecloth and/or a sieve to remove any sand or debris, and boil until 90% of the water has evaporated.

## How long does it take to make sea salt?

A: A typical solar “crop” usually takes five years to produce. Sea salt is made by channeling Pacific Ocean sea water into ponds and letting the wind and sun evaporate it naturally.

## Where do they get sea salt from?

Sea salt is produced through evaporation of ocean water or water from saltwater lakes, usually with little processing. Depending on the water source, this leaves behind certain trace minerals and elements. The minerals add flavor and color to sea salt, which also comes in a variety of coarseness levels.
