The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK.

Also asked, what is the specific heat capacity of water in J kg K?

Accordingly, the temperature at which the measurement is made is usually also specified. Examples of two common ways to cite the specific heat of a substance are as follows: Water (liquid): CP = 4185.5 J/(kg⋅K) (15 °C, 101.325 kPa) Water (liquid): CVH = 74.539 J/(mol⋅K) (25 °C)

What is the value for the specific heat capacity of water?

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation.

## How many joules of energy are required to melt 1 gram of ice?

Problem 2 – The Latent Heat of Fusion for water is 333 Joules/gram. How many Joules of energy do you need to melt all the ice into a pure liquid along the path from B to C on the graph? Answer: For 1 kilogram of ice ,which equals 1000 grams, we need 333 Joules/gram x 1000 grams = 333,000 Joules.

## How much energy is needed to melt one gram of ice?

Melting ice at 0 degrees Celsius: It takes 80 calories to melt 1 gram of ice. If 1 g of ice (at 0 degrees Celsius) is given 80 calories, it will melt and the final temperature of the water will be 0.

## What is the meaning of specific heat?

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat.

## What is meant by the specific latent heat of fusion of ice?

The specific latent heat of fusion (when solid change to liquid) of ice is the amount of heat required to change 1 kg of ice to water without a change in temperature. The specific latent heat of fusion of ice is 0.336 MJ per kg.

## What is the heat of fusion of ice?

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

## What is the density of ice?

This is due to hydrogen bonding dominating the intermolecular forces, which results in a packing of molecules less compact in the solid. Density of ice increases slightly with decreasing temperature and has a value of 0.9340 g/cm3 at −180 °C (93 K). When water freezes, it increases in volume (about 9% for fresh water).

## What is the latent heat of fusion of ice?

Similarly, while ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.

## What is the value of the specific latent heat of fusion of ice?

1 calorie = 4.186 J. Latent heat of vaporization of water = 539 cal/g = 2256 kJ/kg. Latent heat of fusion of water = 79.5 cal/g = 333 kJ/kg. Specific heat of water = 1 cal/g = 4.19 kJ/kg.

## What is meant by specific heat what is meant by latent heat?

The specific latent heat of vaporisation, l, of a substance is the heat needed to change the substance from a liquid at its boiling point into vapour at the same temperature. Specific latent heat of fusion and specific latent heat of vaporisation both have the same symbol, l, and are measured in joules per kilogram.

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

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation.

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

Accordingly, the temperature at which the measurement is made is usually also specified. Examples of two common ways to cite the specific heat of a substance are as follows: Water (liquid): CP = 4185.5 J/(kg⋅K) (15 °C, 101.325 kPa) Water (liquid): CVH = 74.539 J/(mol⋅K) (25 °C)

## What is the unit of specific heat?

Every substance has its own specific heat and each phase has its own distinct value. In fact, the specific heat value of a substance changes from degree to degree, but we will ignore that. The units are often Joules per gram-degree Celsius (J/g °C). Sometimes the unit J/kg K is also used.
