Check Your Understanding Does a given reading on a gasoline gauge indicate more gasoline in cold weather or in hot weather, or does the not matter?
Whether a reading on a gasoline gauge shows more gasoline in cold weather or hot or not effected by temperature?
A gasoline gauge shows more reading in hot weather.
Introduction:
There are some physical properties of matter that change with change in temperature such as dimensions, pressure, color etc. These are known as thermometric properties.
A gasoline gauge shows different reading in different weather when gasoline is filled in. This is because gasoline expands with increase in temperature and contracts with decrease in temperature. The amount of energy produced does not change but the density changes.
In hot weather, as the density would decrease, gasoline would occupy more space and hence, the reading of the gasoline gauge in hot weather would be more than the reading in the cold weather.
Conclusion:
With increase in temperature, gasoline decreases density and thus, the gasoline gauge would show more reading in the hot weather than in the cold weather.
