Exactly what I was looking for. Thank you so much!

Thank you! This helped a lot!
Would you follow the same steps when solving for the initial temperature?

Kelvin Temperature cannot be negative... it ' s must be 37.25 + 273.15 = 310.4

Can you help me out with this one a ballon has a vol 325 mL at 17 degree Celsius. What is temp if volume increases to 392 ml? I got 69.55 degree Celsius?

There's nothing wrong with the result or the method, but it's such a foreign concept to me not to derive the expression for the unknown from the original formula first, and then plug in the numbers. That is, first rearrange the formula to arrive at T2 = T1*V2/V1, then punch the numbers into a calculator in one go. This also eliminates accumulating rounding errors from intermediate results (which isn't an issue in this case, but in general it can be). Just sayin'.

how does 298k times .75 = 74.5 please help that makes no sense
