Question

Interconversion of matter is a constant temperature process Justify

Answer 1

Interconversion of matter is a constant temperature process,
because when matter is changing states,For example:-In ice,
you must have observed during the experiment of melting that the temperature of the system does not change after the melting point is reached, till all the ice melts this happens even though we continue to heat the beaker, that is, we continue to supply heat. This heat gets used up in changing the state by overcoming the forces of attraction between the particles.

Answer 2

Answer:

The process of changing matter from one state to another is called interconversion of states of matter.The interconversion between different states of matter can be brought about by changing the.conditions of temperature and pressure

(i)By changing temperature: By increasing the temperature solids can be converted to liquids and.liquids into gases. This occurs because on increasing the temperature the kinetic energy of particles :

increases and they can move freely. On decreasing the temperature (or cooling), reverse changes take place

For example, ice changes into liquid water at 0°C and water into steam at 100°C (at I atm.

pressure).

(ii) On increasing the pressure, the particles of matter are brought closer. Thus on increasing pressure, gases can be liquefied.
