No.... if you have a volume that can expand (like a balloon), then the volume keeps increasing you increase the temperature. If you have a certain mass of gas and it is heated, it occupies a larger volume. When that mass of gas occupies a larger volume, it becomes less dense... so it floats on colder air. That's how a hot-air balloon works.
Heat doesn't rise... but hot air does!

No. Charles's Law states that the volume of a gas is directly perportional to the Kelvin temperature. That's how a hot air balloon inflates.

in an isochoric process volume is a constant and its independent. but not in general, just in special cases.
http://en.wikipedia.org/wiki/Isochoric_process
here is an example of processes; one is isochoric the other is not.
not isochoric, but volume dependent on temp.
an air mass over the city near the ground picking up
ground heat and begining to warm and rise. its vol
is changing as it rises and depends upon its temp
isochoric. vol not dependent on temp
propane gas in strong solid steel propane tank that
is heating up as the sun rises. the gas in that tank is NOT
changing its volume. volume in that tank is not a variable.
that tank is not going to expand. people have these tanks
in their back yards all over the rural parts

No. P1V1T2 = P2T2V1 - the combined gas law.
If you adust volume, temperature will also be adjusted.
