Explain the types of changes involved in the sequence
Ice cube placed in sun to puddle of water to disappearance of water
Answers
When ice is kept on a cold temperature it stays cooled and in its frozen or crystalline form.
However when it gets exposed to sudden heat, it slowly and gradually meets into water.
On being further exposed to water or any other liquid, it tries to adjust itself with the temperature of that water.
Finally ice melts into liquid form, sand there is a liquid content all over.
One would not be able to find ice in frozen state any further.
Upon being heated, when this is under the exposure of sun's heat, it will evaporate and water will disappear.
Formation of Puddle of water from ice cube is due to melting of the ice. Disappearance of water in presence of sun is known as vapourisation. Melting and vapourisation are both reversible processes. Melting can be reversed by freezing the water whereas vapourisation can be reversed by condensation.
