anonymous one year ago A sample of gas occupying 350. ml at 25°C is cooled to -25°C. What volume will it occupy if the pressure remains constant?

PV=nRT Based on your question what's changing? I only see temperature and volume, the rest is constant So, eliminate moles, pressure, and since R is always constant we'll just remove it anyways. V=T <--only left with this $$\Large \frac{V_1}{T_1}=\frac{V_2}{T_2}$$ v1=$$350. ml*\frac{1L}{1000ml}=.35~L$$ t1=$$25°C +273K=298~K$$ v2= Unknown t2=$$-25°C +273K=248~K$$ $$\Large \frac{.35~L}{298~K}=\frac{V_2}{248~K}$$ Solve for v2
