A gas in a large syringe has a volume of 300ml at 45°C. The temperature is lowered to 30°C. What is the new volume of the gas in the syringe? (N and p are constant). Hint:Convert temperature to kelvin before calculating (°C+273=K)

V1=300ml

V2= x ml

T1= 45 Celsius

T2= 30 celcius

Do the math

you will get

318x=90900

divide by 318

x=285.8 ml (rounded)

Explanation:

you have to add 45 and 30 (separately because the temp. has to be in kelvin) to 273... so V2 equals 2858.8 ml

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
