## What is meant by sensible heat?

Sensible heat When an object is heated, its temperature rises as heat is added. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.

## What is the latent heat of water?

A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g−1 more energy than ice at the same temperature. This energy is released when the liquid water subsequently freezes, and it is called the latent heat of fusion.

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

4.187 kJ/kgK

Specific heat (Cp) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)

## What is the formula of sensible heat?

Heat that results in a temperature change is said to be “sensible” (although this term is falling out of favor)….introduction.

Q = | heat evolved (+ heat absorbed, − heat released) [J] |
---|---|

m = | mass [kg] |

c = | specific heat capacity [J/kg°C or J/kgK] |

∆T = | temperature change [°C or K] |

## What is a sensible heat factor?

Sensible heat factor is the ratio of sensible heat and Total heat. Sensible heat is the heat which increases or decreases the temperature of the body. Latent heat is the heat which increases the specific humidity without increasing or decreasing the temperature of the body.

## Is the heat content of liquid water sensible heat?

The heat content of liquid water is sensible heat. The enthalpy change accompanying the phase change of liquid water at constant temperature is the latent heat. 3. Saturated steam is at equilibrium with liquid water at the same temperature.

## Why is latent heat called so?

The latent heats are the amount of heat energy needed by a compound to change its state. They are called latent because there are no temperature differences observed. The latent heat exists whenever a compound changes its state. When it goes from solid to liquid it is called the latent heat of fusion.

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

4.184 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 specific heat of liquid water?

4182 J/kg°C.

Water has a specific heat capacity of 4182 J/kg°C.

## How do you calculate sensible heat of water?

For water, after doing the required conversions and inputting the correct specific heat, the sensible heat equation becomes: Qwater = 500 * GPM * (Leaving Water Temperature – Entering Water Temperature).

## What is the specific latent heat of water?

Water has latent heat of vaporization of 540 calories per gram, the amount of heat energy that is necessary to convert 1 g of liquid water at 100°C to steam at 100°C, or 40.71 kJ/mol or about 2,260 kJ/kg water.

## How does water absorb and release heat?

Water going from a gas to a solid: Deposition. In each phase change there will be either an absorption or release of latent heat. Latent heat absorption cools the surrounding air while latent heat release warms the surrounding air.

## What are the uses of the specific heat of water?

Application of Specific Heat Capacity Car radiator. Water is pumped through the channels in the engine block to absorb heat. Cooking utensils. Cooking utensils are made of metal which has low specific heat capacity so that it need less heat to raise up the temperature. Thermal Radiator. Thermal radiators are always used in cold country to warm the house. Sea Breeze. Land Breeze.

## Does water have a high specific latent heat?

Water has a high latent heat of fusion , so turning water into ice requires the removal of more energy than freezing liquid oxygen into solid oxygen, per unit gram. Latent heat causes hurricanes to intensify. Air heats as it crosses warm water and picks up water vapor. As the vapor condenses to form clouds, latent heat is released into the
