Demonstrate an activity to show latent heat of vaporization?
Answers
Answer:
The action to demonstrate how latent heat of vaporization functions,
Things required are: family unit electric container, tip stacking electric parity, timing gadget.
Ventures to do:
(1). Note the power rating of electric container
(2). Fill the container with warm water and spot it on electric equalization.
(3). Associate the container with primary supply and enable the water to bubble.
(4). At the point when crease comes, take the perusing of intensity of electric container
(5). Begin the clock till the mass is diminished to 50g and again note the perusing.
(6). Stop the clock and ascertain time slipped by
Toward the end we can comprehend that a gigantic measure of vitality is required to secretive water at 100°C to steam at a similar temperature.

Matter can change from one form to other form i.e from solids to liquids to gases.
The phenomenon of the change of matter from one state to another and back to original state is known as interconversion of the sates of matter.
Matter can be changed from one state to another by changing temperature or pressure.
# Change in state of water
When heat energy is supplied to ice it changes into water and then to vapor. If we cool the steam it gets converted into water and further cooling of water changes into ice.
Here the heat energy is used up in changing the state of matter. the heat is used to increase the kinetic energy of the particles of ice to such an extent that they break away from the rigid lattice structure of the solid form, ice, and move around freely to form the liquid form, water. So, until all the ice has melted, the heat absorbed does not raise the temperature of the ice-water mixture. In the same way the temperature does not change while a liquid is boiling. This heat, which does not raise the temperature of the body, is called Latent Heat.
Melting or Fusion
Melting is the process where solid changes into a liquid at a particular temperature.
Melting point
The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.
# Melting points of some solids
Solids Melting point
1. Ice (H2O) 00C
2.Sodium chloride (NaCl) 8000C
3. Iron 15350C
Latent heat
The word 'latent' means hidden. The characteristic amount of energy absorbed or released by a substance during a change in its physical state that occurs without changing its temperature is known as latent heat.
Latent heat of fusion
Latent heat of fusion is the amount of heat energy required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point.
Boiling
Boiling is the process where a liquid changes into a vapor at a particular temperature.
