Vedclass · Answer

(D) Different states of matter exhibit the following characteristics: $(i)$ Solids have definite volume and definite shape. $(ii)$ Liquids have definite volume but not a definite shape. They take the shape of the container in which they are placed. $(iii)$ Gases have neither definite volume nor definite shape. They completely occupy the container in which they are placed. These three states of matter are interconvertible by changing the conditions of temperature and pressure. $	ext{SOLID}$ $\xrightarrow[	ext{cool}]{	ext{heat}} 	ext{LIQUID}$ $\xrightarrow[	ext{cool}]{	ext{heat}} 	ext{GAS}$ On heating,a solid usually changes to a liquid,and the liquid on further heating changes to the gaseous (or vapour) state. In the reverse process,a gas on cooling liquefies to the liquid state,and the liquid on further cooling freezes to the solid state.
