Question

thermal expansion in daily life-10 examples

Answer 1

• When you want to open a tight jar, it is recommended that you run it under hot water. This expands the lid ever so slightly to relieve all the stress and friction and the jar opens up easily.
• Train tracks are put in pieces and you can notice a small gap between them. You can hear that gap in the train’s rhythm. The gap is to make it easy for the tracks to expand and contract without putting undue stress on each other.

Answer 2

Thermal expansion examples are:-

1. The behavior of gasoline on a hot day provides an example of liquid thermal expansion in response to an increase in temperature. If car tank is filled and it left to sit on the sun, then gasoline expand in volume.
2. The gas gauge on a car.People are much more likely to run out of gas in the summer than the winter. Why is that? Well, the gas in your car expands, like anything else, and changes the reading on your fuel gauge. In the summer, the gas takes up more space in the tank, and so when it reads empty, there's significantly less fuel left in the tank than in winter. Maybe you get an extra 35 miles after it hits empty in the winter, but that won't be the case in the heat of summer. So, be careful out there! Don't be the fool who has to walk three miles to the gas station because they don't know about thermal expansion.
