## What is the temperature of sea water when it started to boil?

At sea level, pure water boils at 212 °F (100°C).

At the lower atmospheric pressure on the top of Mount Everest, pure water boils at about 154 °F (68°C).

In the deep oceans, under immense pressure, water remains liquid at temperatures of 750°F (400°C) around hydrothermal vents..

## What is the equation for specific latent heat?

Specific latent heat of fusion Eh means energy, equals m for mass, times l. l is the specific latent heat of fusion for that material. So the formula tells us how much heat energy is needed to go into a material to change it from a solid to a melted liquid. If you apply heat to ice, it will melt.

## Does salt water boil at a lower temperature?

Adding salt to water is going to do two things to water’s physical properties: it will raise the boiling point and it will lower the specific heat. These two changes actually work against each other. Raising the boiling point will make the water boil slower.

## What is the specific heat capacity of sugar?

Constant pressure heat capacity of solidCp,solid (J/mol*K)425.5Temperature (K)298.15ReferenceAnderson, Higbie, et al., 1950CommentT = 298 to 363 K.; DH

## What is the specific heat capacity of salt 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.

## How do you calculate specific heat capacity?

The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.

## Which will boil at higher temperature tap water or sea water?

Sea water because it contains more salt. So that it takes much energy to break down its molecules.

## Does the sun heat saltwater and freshwater at the same rate?

One thing to keep in mind is that heat capacity is based on the mass of a material and not its volume. That is to say, given the same amount of heat added, the same mass of saltwater will heat faster than freshwater.

## How do you find the specific heat of sodium?

Well the formula for specific heat is S=E/M(T2-T1). S=specific heat(j/KgºK), E=energy in jules, M=mass in Kg, T2=temperature after reaction(kelvin) an T1=temperature before reaction(kelvins).

## How does the concentration of salt in water affect the specific heat capacity?

When we dissolve NaCl in water, the ions are held in a rigid cage of water molecules. … It takes less energy to activate these molecules, so the specific heat of the water decreases. The greater the concentration of NaCl, the lower the specific heat capacity of the solution.

## Why does salt water have a lower heat capacity?

Salt/ sugar water contains less heat than water, so it cools and heats quickly. The ions “trapping” water molecules plays a role, but there is another, more simple explanation: the dissolved substance also physically gets in the way.

## What is the specific heat capacity of water in J kg C?

4,200 Joules per kilogramThe specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

## How does specific heat capacity affect the rate of cooling?

Heat capacity is related to a substance’s ability to retain heat and the rate at which it will heat up or cool. For example, a substance with a low heat capacity, such as iron, will heat and cool quickly, while a substance with a high heat capacity, such as water, heats and cools slowly.

## What is the SI unit of specific heat capacity C?

joulesIn SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin. It may also be expressed as J/kg·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too.

## What’s the specific heat capacity of water?

6 joules, meaning that the specific heat capacity of water is 4179. 6 J·kg−1·K−1. The specific heat often varies with temperature, and is different for each state of matter.

## Why does salt water boil at higher temperature?

In order for water to boil, its vapor pressure has to equal the pressure of the atmosphere, Giddings said. … When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.

## What is the melting point of salt?

801 °CSodium chloride/Melting point

## What is excess heat capacity?

in other words the excess heat capacity is associated with the component of the internal energy due to the intermolecular potential, and for that reason it is also known as the configurational heat capacity. Given that the excess internal energy for a pair potential is given by (Eq.

## Does salt water have a higher heat capacity?

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 does sugar affect the specific heat capacity of water?

The sugar solution has a higher specific heat capacity than pure water. So for an equivalent temperature drop, more energy has to be lost.
