a student argues"During summer it is more profitable to buy fuel(petrol/diesel)around 9 o'clock in the morning ".verify the validity of the statement.explain your reasons!!!

Substances expand on heating.

 

During summer the temperature of the surroundings is high.

 

A liquid (fuel) will expand more under this heat and occupy more volume.

 

If one buys fuel in mid afternoon, the fuel would have expanded to a greater extent and hence less fuel will occupy more volume of the fuel tank. Hence, one should buy the fuel in early hours of the morning.
