Can someone please help me with these two questions? A 550.0 mL sample of nitrogen gas is warmed from 77 degrees C to 86 degrees C.
Find its new volume if the pressure remains constant.

A gas occupies 1.00 L at 0.00 degrees C. What is the volume at 333.0 degrees C?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
