Question
Two glasses have stuck together into each other.
How will you loosen them by the use of:
(i) hot water (ii) cold water?
Solution
Place the two glasses in hot water, such that there is no water in the inner glass. The outer glass expands because of hot water and hence a gap is set up between the two glasses and thus we can take the glass out.
If we have cold water, then put the cold water in the inner glass. The cold water makes the inner glass contract leaving a gap between the two glasses and thus we can take the other glass out.
