Gas Laws QUESTION ANSWER 1.71 L The gas laws describe the behavior of gases under specific conditions of temperature, pressure, and volume. Three gas laws show the relationship between two variables when all others are held constant: Boyle's law (pressure and volume are inversely proportional), Charles's law (volume and temperature are directly proportional), and Gay-Lussac's law (temperature and pressure are directly proportional). 2.73 L 1.47 L The three laws can be combined into one law, called the combined gas law. 4.24 L IDON'T KNOW YET A sample of argon has a volume of 0.983 L. a pressure of 2.50 atm, and a temperature of 32 °C. What is the new volume. if the new pressure is 1.55 atm and the new temperature is 55°C? O Type here to searchExplanation / Answer
Gas law equation for one condtion of temperature (T1), pressure (P1), Volume (V1) to different conditions of temperature (T2), pressure (P2) and Volume (V2) can be written as
P1V1/T1= P2V2/T2
V2= P1V1T2/(P2T1) (1)
Where Pressure is in atm, volume is in Liters, and temperature has to be in K
Given P1= 2.5 atm, V1=0.983L, T1= 32 deg.c, converting into K, T1= 32+273= 305K
P2= 1.55 atm, T2=55deg.c= 55+273= 328K
Substituting the values in Eq.1 , V2= 2.5*0.983*328/(1.55*305) =1.71 L.
Volume at the given conditions of P2= 1.55 atm and T2= 55 deg.c is 1.71 L. ( A is correct)
