Transfer of heat: To carry heat from one part of an object to its other part or from one object to another object is called transfer of heat. Like if we dip a steel spoon in a cup of hot tea, we find that the temperature of a spoon rises and it becomes hot. The heat transfers from an object at higher temperature to another object at lower temperature. The transfer of heat stops when the two objects attain same temperature. The heat can be transferred from a hot to cold object in three different ways:

a. By conduction: The process by which heat is transferred from the hotter end to the colder end of an object is known as conduction. The conduction process takes place only in solids.

b. By convection: The process by which heat is transferred from the hotter parts of a liquid to its colder parts by the movement of the liquid itself is known as convection. For e.g. water is a good convector.

c. By radiation: The process of transfer of heat of hot electric bulbs to our hand held below it is called radiation.

During the day, the land gets heated faster than the water. The air over the land becomes hotter and rises up. The cooler air from the sea rushes in towards the land to take its place. The warm air from the land moves towards the sea to complete the cycle. The air from the sea is called the sea breeze.
The water cools down more slowly than the land. So, the cool air from the land moves towards the sea.This is called the land breeze.

Two liquids are said to be miscible if they completely mix and thus form a homogeneous mixture. For example ethanol and water, benzene and carbon tetrachloride etc
Immiscible liquids are those which do not mix completely. Hence a mixture of two immiscible liquids is not homogeneous but heterogeneous. For example benzene and water.

Rain with a high acid content is called acid rain. It is formed by the acidic gases present in the atmosphere which are fairly soluble in water so they become acidic.

Yogita Ingle 7 years, 5 months ago

Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6. When the air becomes more polluted with nitrogen oxides and sulphur dioxide the acidity can increase to a pH value of 4. Some rain has even been recorded as being pH value 2.
