Class: IX
Subject: CHEMISTRY
 
1. Answer question numbers 1(a) - 1(d) on the basis of your understanding of the following paragraph and the related studied concepts. On increasing the temperature of solids, the kinetic energy of the particles increases. Due to increase in kinetic energy particles start vibrating with greater speed. The energy supplied by heat overcomes the forces of attraction between particles. The particles leave their fixed position and start moving freely. At a stage solid changes into liquid. Heat energy supplied to overcome intermolecular forces remains as hidden energy and no rise in temperature is seen.
 
1(a) On melting of ice, there is decrease in volume instead of increase. Why? 
 
1(b) Steam causes more severe burns as compared to boiling water. Give reason. 
 
1(c) Arrange the following in increasing order of kinetic energy:
 
Iron nail, oxygen gas, milk 
 
1(d) Define latent heat.
