2- A gas has a volume of 500 mL at a temperature of -73.0 °C. What volume will the gas
occupy at 27.0°C?

750ml

Explanation:

Using charle's law

V1/T1=V2/T2

V1= 500ml

T1= -73⁰C

V2= ?

T2=27⁰C

We can see that the temperature is in Celsius

Now,we will convert to Kelvin

Kelvin= 273+ Celsius

So convert the Celsius value to Kelvin

For T1= 273+(-73)

T1= 273-73

T1= 200K

For T2= 273+27

T2= 300K

V1/T1=V2/T2

500/200=V2/300

Cross multiply

200×V2=500×300

200V2= 150000

V2= 150000/200

V2= 750ml

So,

750ml of gas will occupy at 27⁰C
