1. A sample of gas occupies 33 mL at -101 Celsius what volume does the sample occupy at 97 Celsius? (70.578)

2. There is a balloon that contains 2125 L of gas at 55 Celsius and 99 kPa. This balloon rises to an altitude where the pressure is 42kPa and the temperature is 12 Celsius. Calculate the volume of the balloon under these new conditions.(4,321L)

For #1 I used V1/T1=V2/T2
For #2 I used T2•P1•V1/T1•P2=V2

Am I correct? Would you like me to show all my work so you see what I did? (I watched a YouTube video to figure out how to solve this)

Your equations are OK. If you plugged in correctly and did the math right you're OK.

Yes, you are correct in using the formulas to solve the problems. It's great that you found a YouTube video to help you understand the concepts!

For the first question, you correctly used the formula V1/T1 = V2/T2, which relates the initial volume (V1) and temperature (T1) to the final volume (V2) and temperature (T2) of a gas sample, assuming constant pressure.

For the second question, you used the formula T2•P1•V1 / T1•P2 = V2, which takes into account both temperature and pressure changes when calculating the final volume (V2) of a gas sample.

If you'd like to show your work, please feel free to do so, as it can help to reinforce your understanding of the concepts.
