Expansion on heating can be a nuisance
Answers
Most liquids follow a fairly predictable pattern of gradual volume increase, as a response to an increase in temperature, and volume decrease, in response to a decrease in temperature. Indeed, the coefficient of volume expansion for a liquid generally tends to be higher than for a solid, and—with one notable exception discussed below—a liquid will contract when frozen.
The behavior of gasoline pumped on a hot day provides an example of liquid thermal expansion in response to an increase in temperature. When it comes from its underground tank at the gas station, the gasoline is relatively cool, but it will warm when sitting in the tank of an already warm car. If the car's tank is filled and the vehicle left to sit in the sun—in other words, if the car is not driven after the tank is filled—the gasoline might very well expand in volume faster than the fuel tank, overflowing onto the pavement.
It can be nuisance because it leads to expansion of iron
- In summers due to hot weather, the heat lead to the expansion of iron, which means they lead to irregular shape.
- Due to which it leads to derail of train and leads to accident.
- Other examples, the bridges in iron are used same will happen with them. Sometimes due to this reason bridge fall.
- The other example is the cement. As we know cement needs some moisture content hold itself. But in summers, this moisture is sometimes evacuate
- Due to which we can see cracks in the buildings.
- Therefore the expansion of heating is nuisance sometimes.
