Why do steel bars expand when heated make use of kinetic theory of matter to support the answer?
The temperature of steel is determined by the amount of vibration of its constituent atoms. Hotter atoms vibrate more. And when they vibrate more, they take up more space. Hence, the steel expands.
What physical state is steel at room temperature?
Steel is not an element it is a metallic alloy containing iron, carbon and other additives. At standard temperature and pressure it is a solid.
Do liquids expand uniformly with rise in temperature?
No, liquids do not always expand uniformly with temperature. Generally, liquids expand as they are heated, but the expansion may not be uniform due to factors such as the specific properties of the liquid and the conditions under which it is heated.
Will an inert gas expand and contract with temperature?
It will contract.
How much does a bearing expand when heated?
The amount a bearing will expand when heated depends on factors such as material composition and temperature. However, typically a bearing will expand around 0.0005 inches per inch of diameter for every 100°F increase in temperature.
