प्रश्न
Explain the following observation.
The type of an automobile is inflated to slightly lesser pressure in summer than in winter

उत्तर
The pressure of air is directly proportional to the temperature. Since the temperature is higher in summer than in higher, the pressure of the air in the tube of the lyre is likely to be quite high as compared to winter. It is quite likely that the tube may burst under high pressure in summer, Therefore, it is advisable to inflate the types to lesser pressure in summer than in winter.
