## algebra

According to Boyle’s law, the volume V of a gas varies inversely to the pressure P exerted by the gas. The volume of a given gas under a pressure of 32 kg per cm2 is 200 cm3. What will be the volume of this gas when the pressure exerted is 40 kg per cm2?

for this question A sample of air has a volume of 140.0 mL at 67 degrees celcius. At what temperature would its volume 50.0 mL at constant pressure I did 140.0 ml... 67+273=340 T2... 50.0 140.0=50.0 340=T2 340*50.0/140.0=121.4 This question i don't get
