A 4.44 l container holds 15.4 g of oxygen at 22.55°c. what is the pressure?

1 answer:

5 0

We will use the ideal gas equation:
PV = nRT, where n is moles and equal to mass / Mr
P = mRT/MrV
P = 15.4 x 8.314 x (22.55 + 273) / 32 x 4.44
P = 266.3 kPa

Suppose 1.4 mol of an ideal gas is taken from a volume of 2.5 m3 to a volume of 1.0 m3 via an isothermal compression at 27°C. (a

zysi [14]

Answer:

Part a)

Q = 3198 J

Part b)

It is compression of gas so this is energy transferred to the gas

Explanation:

Part a)

Energy transfer during compression of gas is same as the work done on the gas

In isothermal process work done is given by the equation

$W = nRT ln(\frac{V_2}{V_1})$

now we know that

n = 1.4 moles

T = 27 degree C = 300 K

$V_2 = 2.5 m^3$

$V_1 = 1 m^3$

now we have

$W = (1.4)(8.31)(300)(ln\frac{2.5}{1})$

$Q = 3198 J$

Part b)

It is compression of gas so this is energy transferred to the gas
