Question

A gas sample collected at 35.0°C and a pressure of 710 torr has a volume of 200 mL. The temperature and pressure are changed, and the gas is compressed to 150 mL. The new temperature is 40.0°C; what is the new pressure?

Gas laws:

V₁P₁ = V₂P₂

V₁T₂ = V₂T₁

V₁P₁T₂ = V₂P₂T₁

?1?1=?2?2V1n1=V2n2

??=???(?=0.0821?⋅??????⋅?)PV=nRT(R=0.0821L⋅atmmol⋅K)

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
