No. If a fixed quantity of any gas is heated, it will either expand or the pressure will increase. This is called Boyle's Law.

So, if you have a balloon outside in the cold, and you bring the balloon inside, it will expand somewhat, because the balloon _CAN_ expand. If you have a rigid vessel and you heat it, the pressure increases.

This is the basic idea behind a pressure cooker; a strong metal container with a lid that can tightly seal the pot. As you increase the temperature, the pressure will also increase.
