Air is composed of several different gases most notably nitrogen oxygen and carbon dioxide but the particular gas involved does not matter.
Example of gas expanding when heated. 1 If you have ever tried to unscrew a stuck lid off a glass jar youll appreciate this expansion effect. As the air inside the flask contracts the water rises up the tube. We make use of the expansion of a liquid in the most common type of thermometer.
The gasoline cools the steel tank when it is filled. 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. For example when a flask with a long narrow stem containing enough liquid to partially fill the stem itself is placed in a heat bath the height of the liquid column in the stem will initially drop followed immediately by a rise of that height until the whole system of flask liquid and heat bath has warmed through.
The balloon gets larger and larger until the rubber cannot hold the gas in. Okay one more example. Well the gas in your car expands like anything else and.
2013-07-26 1836. If it is in say a balloon then the greater pressure pushes outward on the balloon and makes it expand. If the cars tank is filled and the vehicle left to sit in the sunin other words if the car is not driven after the tank is filledthe gasoline might very well expand.
When the temperature is low the mercury does not take up much room and the level in the tube is low. What is an everyday example in which you observe a gas expanding when heated. Here are five examples.
All gases behave identically with an identical increase in temperature as long as the other conditions are also identical. Observe the bubbles of air inthe water. Explosions occur due to a rapid change in volume like the case of the.
