When atoms are heated, what happens to their $speed$?

anonymous · Answer

Im lost in this subject lol

jfraser · Answer

you should have studied a little bit of kinetic theory first, am i right?

anonymous · Answer

Probably. Chemistry isnt a easy subject for me. Just saying.

jfraser · Answer

ok, so in general, do you know what happens to the speed of atoms when they are heated?

anonymous · Answer

No not really. Please explain.

jfraser · Answer

how would you move if you were put on a hot stove?

anonymous · Answer

Fast

jfraser · Answer

so what do you think happens to atoms when they are heated?

anonymous · Answer

They move faster

jfraser · Answer

exactly

jfraser · Answer

since it's a gas, the atoms of a gas are free to move in straight lines until they hit the walls of the container.  The collisions with the wall create pressure.

jfraser · Answer

if the gas is heated, the atoms move faster.

if the atoms move faster, they hit the wall $harder$ and $more \space often$

jfraser · Answer

what should happen to the pressure (which is caused by the collisions) when the gas is heated?
