Question

Give reason:
a) Soda bottles are often labelled “store in cool and dry place”.
b) Balloons pops out during hot summer more frequently than in winter.
c) During winter football filled with air reduces to its original size when taken outdoors.

Answer 1

a) Soda bottles are often labelled “store in cool and dry place”. The carbon dioxide filled in soda bottles on exposure to heat, expands because the gas inside the bottle expands as temperature rises.

b) Balloons pops out during hot summer more frequently than in winter. As the temperature increases in summer, the volume of the gas filled in balloon also increases which makes the balloons to pop out.

c) During winter football filled with air reduces to its original size when taken outdoors. When football is taken out, its temperature decreases so the volume to gas filled also decreases.
