Question

A gas has an initial volume of 168 cm3 at a temperature of 255 K and a pressure of 1.6 atm. The pressure of the gas decreases to 1.3 atm, and the temperature of the gas increases to 285 K.What is the final volume of the gas?

Answer 1

I do not have a calculator, but let’s think...

Imagine a ballon with a certain amount of gas. When you decrease the volume by squeezing the balloon, you increase the pressure.

Which means volume is inversely proportional to the pressure:
PV=PV

Now to speed things up because class is about to start :/

PV/T=PV/T, I think

Tip: check your units and any questions let me know
