As a sample of gas is heated, its volume increases. Why does this occur?

A. The increased speed of the gas particles makes them collide with each other with greater force and bounce farther apart -- increasing the total volume occupied by the gas particles.
B. The gas decomposes into more molecules which makes them collide with each other with greater force and bounce farther apart.
C. The gas softens when heated which increases the total volume occupied by the gas particles.
D. The entire universe is expanding.

i am sorry do not know for answer

anonymous · Answer

must be A i think sweet

sweetburger · Answer

most likely A. im almost certain as when gas particles are heated they gain kinetic energy and will take up more space

Well, if you think about it, assuming an ideal gas: $\sf \color{red}{PV = nRT}$
As you can see: P = V
so as pressure increases, volume increases also. It is directly proportional.
