## Which has the highest specific heat?

WaterWater has the highest specific heat capacity of any liquid.

Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius..

## What is specific heat used for?

Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.

## What is an example of heat of vaporization?

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.

## What is the heat of vaporization of water?

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 specific and latent heat?

Specific heat: = energy required to change a unit mass of a material by 1°C. Units: energy per unit mass per degree. Latent heat = energy required to change the state (gas, liquid, solid) of a unit mass of material.

## How do I calculate specific heat?

Specific HeatFor a mass m = gm = kg.with specific heat c = cal/gm°C = joule/gm°C,initial temperature Ti = °C = K = °F.and final temperature Tf = °C = K = °F,Q = calories = kcal = x 10^ calories.Q = joules = x 10^ joules.

## Is heat of vaporization positive or negative?

The enthalpy of condensation (or heat of condensation) is by definition equal to the enthalpy of vaporization with the opposite sign: enthalpy changes of vaporization are always positive (heat is absorbed by the substance), whereas enthalpy changes of condensation are always negative (heat is released by the substance) …

## What is the formula 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.

## How do you calculate sensible heat?

Sensible heating Btu is measured by the ageless formula CFM x Delta-T x 1.08. To measure heating Btu, multiply the measure supply airflow (in cfm) by the temperature change from the average supply register temperature to the average return grille temperature, and multiply this total by the formula constant of 1.08.

## What is Latent Heat example?

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.

## What is the difference between specific heat capacity and the latent heat of vaporization?

Specific heat capacity is the heat required to raise the temperature of unit mass of a substance by 1°C(1K). … Latent heat of the substance is the heat required to change the phase of the substance without any change in the temperature.

## What is the difference between specific heat and heat capacity?

Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. … Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

## Does heat of vaporization change with pressure?

The heat of vaporization diminishes with increasing temperature and it vanishes completely at a certain point called the critical temperature (Critical temperature for water: 373.946 °C or 705.103 °F, Critical pressure: 220.6 bar = 22.06 MPa = 3200 psi ).

## What is meant by specific heat of vaporization?

Definition of heat of vaporization. : heat absorbed when a liquid vaporizes specifically : the quantity of heat required at a specified temperature to convert unit mass of liquid into vapor.

## What is heat capacity explain?

Heat capacity, ratio of heat absorbed by a material to the temperature change. It is usually expressed as calories per degree in terms of the actual amount of material being considered, most commonly a mole (the molecular weight in grams). The heat capacity in calories per gram is called specific heat.
