As a gas is compressed in a cylinder, the pressure of the gas

As a gas is compressed in a cylinder its pressure

As the compression proceeds the volume of the chamber is decreasing and since mass is same, density increases. Similarly as volume decreases the number of gas molecules colliding with the walls increases as the density increases, so the pressure on the wall also increases.

When a gas is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws. When a gas is compressed rapidly, its volume decreases leading to increase in temperature.

Also the pressure increase which also increases the randomness of the gas molecules which start to collide more frequently and thus the temperature rises .

just to make you understand what randomness affects - you would have noticed that you often sweat in a small room filled with people but it’s cooler if the same number of people are there in a bigger room.

Explanation:

answer: h+ its less than oh

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
