Calculate the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L.
Aleonysh [2.5K]

Answer: 15.5^0C

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 0.987 atm

V = Volume of gas = 12 L

n = number of moles = 0.50

R = gas constant =0.0821Latm/Kmol

T =temperature =  ?

T=\frac{PV}{nR}

T=\frac{0.987atm\times 12L}{0.0820 L atm/K mol\times 0.50mol}=288.5K=(288.5-273)^0C=15.5^0C

Thus the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L is 15.5^0C

1.Explain the difference between a FIXED VOLUME and an ELASTIC VOLUME
In-s [12.5K]

Answer:

Fixed volume is the property of liquid and solid which means that the volume of both solid and liquid remain fixed or constant under fixed temperature and pressure.

Elastic Volumes makes it easy to dynamically increase capacity, tune performance, and change the type of any new or existing current generation volume with no downtime or performance impact.
