I was just doing homework for chem., and just thought of posting one of the problems up here, just to see if any of u smart ones can do it?? ive done it already and have the right answer, but can u do it?? here it is....
A tank of compressed carbon dioxide has a temperature of 23.6C and a volume of 31.4 L. The carbon dioxide is completely transferred into a smaller tank that has a volume of 25.0 L. Assuming none of the carbon dioxide escapes during the transfer, what is the tempreature of the carbon dioxide in the smaller tank if the temperature is lowered to achieve the same pressure as in the larger tank??

Another one. This one is easier...
What will be the volume of a gas sample at 309K if its volume at 215 is 3.42 L? Assume the pressure is constant.
