Question

Write the sequence of change in state of matter when steam is formed?

Answer 1

• Liquid s on heating, the particles keep gaining more kinetic energy and move even faster till the temperature reaches the boiling point.
• If heat is continued beyond the boiling point, the kinetic energy of the particles become so large.
• They overcome the inter-particle force of attraction and break away and move out into the space available, thus changing liquid into gaseous state.

$$\begin{gathered} \mathrm{Liquid}\stackrel{\mathrm{heat}}{\to }\mathrm{kinetic}\mathrm{energy}\mathrm{of}\mathrm{the}\mathrm{particle}\mathrm{increases}\stackrel{\mathrm{heat}}{\to }\mathrm{Reaches}\mathrm{boiling}\mathrm{point}\mathrm{of}\mathrm{matter}\stackrel{\mathrm{heat}}{\to } \\ \mathrm{Liquid}\mathrm{changes}\mathrm{into}\mathrm{gas} \end{gathered}$$
