# What is the specific heat capacity of water in kJ?

## What is the specific heat capacity of water in kJ?

approximately 4.187 kJ/kgK
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.187 kJ/kgK.

What is the heat capacity of water?

4,184 Joules
One of water’s most significant properties is that it takes a lot of energy to heat it. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C.

### What is the heat capacity of water in J mol K?

The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.

How do you calculate specific heat capacity of water?

The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.

#### What is the specific heat of water in J?

4.184 J/g-K
The units of specific heat in the SI system are J/g-K. Because there are 4.184 joules in a calorie, the specific heat of water is 4.184 J/g-K.

What is the heat vaporization of water?

around 540 cal/g
Heat of vaporization of water That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water’s heat of vaporization is around 540 cal/g at 100 °C, water’s boiling point.

## What is the latent heat of vaporisation of water?

For example, the latent heat of vaporization of water is 540 cal/g and the latent heat of freezing of water is 80 cal/g.

Is J kg K the same as J KGC?

Assuming you mean kJ/(kg K) and kJ/(kg C), where K stands for a unit on the Kelvin temperature scale and the C for a unit on the Celsius temperature scale, the answer is yes because the Celcius and Kelvin scale have the same unit but different zero points.

### What is the heat capacity of 250g of water?

heat capacity of water- `4.2 J//g^(@)C`. A solid of mass 250 g at `90^(@)C` is dropped in a calorimeter containing 100 g of water at `15^(@)C`.

How much energy does it take to vaporize water?

540 calories per
… energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.

#### How many joules does it take to evaporate water?

2260 J g-1
For water at its boiling point of 100 ºC, the heat of vaporization is 2260 J g-1. This means that to convert 1 g of water at 100 ºC to 1 g of steam at 100 ºC, 2260 J of heat must be absorbed by the water.
