What Is The Temperature At Which Latent Heat Of Water Is Zero?

by | Last updated on January 24, 2024

, , , ,

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.

Is defined as the point at which latent heat becomes zero?

Variation with temperature (or pressure)

As the temperature (or pressure) rises

to the critical point

, the latent heat of vaporization falls to zero.

Can latent heat become zero?

Latent heat of vaporization is the heat required to change the state of a substance from liquid to vapour or heat given out when it changes from vapour to liquid. … Therefore, the latent heat

becomes zero at the critical point

.

What is the latent heat of water at ordinary temperature?

The latent heat of vaporization for water at room temperature is

2430 J/g

.

What is the latent heat capacity of water?

Substance Specific latent heat of fusion (kJ/kg) Specific latent heat of vaporisation (kJ/kg) Water

334


2,260
Lead 22.4 855 Oxygen 13.9 213

What is the latent heat of steam?

As the latent heat of steam at atmospheric pressure is

2257 kJ/kg

the amount of flash steam produced will be 299/2257 = 0.133 kg/kg of condensate.

What is latent heat in simple words?

latent heat,

energy absorbed or released by a substance during a change in its physical state

(phase) that occurs without changing its temperature. … The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.

How can you detect latent heat?

Measuring latent heat

Latent heat can be

measured from a or cooling curve line graph

. If a heater of known power is used, such as a 60 W immersion heater that provides 60 J/s, the temperature of a known mass of ice can be monitored each second. This will generate a graph that looks like this.

What are the three types of latent heat?

  • Latent Heat of Fusion,
  • Latent Heat of Vaporization,
  • Latent Heat of Sublimation.

Is there any relation between latent heat and Regelation?


Yes there is relationship between latent heat

and regelation . (i) The amount of heat energy absorbed or relased during change of state in called Latent heat. (ii) The phenomenon in which ice converts to liquids due to applied pressure and then reconverts to ice once the pressure is removed is called Regelation.

Does latent heat of vaporization change with temperature?

Note that

a latent heat is associated with no change in temperature

, but a change of state. Because of the high heat of vaporization, evaporation of water has a pronounced cooling effect and condensation has a warming effect (Kramer, 1983, p. 8).

Why is latent heat important?

Latent heat is

an important source of energy in the development of thunderstorms and hurricanes

. Water vapor strongly absorbs infrared radiation, making it an important gas in the Earth's heat-energy balance. In fact water vapor is the largest contributor to the greenhouse effect on Earth.

What is latent heat Class 9?


The heat energy which has to be supplied to change the state of a substance

is called its latent heat. Latent heat does not raise (or increase) the temperature. But latent heat has always to be supplied to change the state of a substance . The word ‘latent' means ‘hidden'.

Does water have a high latent heat?

Closely related to water's unusually high heat capacity are its

high latent heat of melting

and latent heat of vaporization. … The amount of heat required to convert 1 g of ice to 1 g of water, 80 Cal, is termed the latent heat of melting, and it is higher for water than for any other commonly occurring substance.

What is sensible heat water?

Sensible heat of water: It is defined as

the quantity of heat absorbed by 1 kg ofwater when it is heated from 0°C (freezing point) to boiling point

.It is also called total heat (orenthalpy) of water or liquid heat invariably. It is reckoned from 0°C where sensible heat is takenas zero.
