0.3 kg air inside 42.9 litres cylinder has a temperature is 31.0°c. the r value for air = 287 j/kg/k. what is the pressure of air inside the cylinder? (k pascal)

Pressure = 610.125 kPa

Explanation:

Given:

Mass of the air, m = 0.3 kg

Volume of the cylinder, V = 42.9 litres = 42.9 × 10⁻³ m³

R value for the air = 287 J/kg/K

Temperature, T = 31.0° C = 304 K

Now,

we know the ideal gas equation is given as :

PV=mRT

where,

P is the pressure

on substituting the values, in the above formula

we get

P × 42.9 × 10⁻³ = 0.3 × 287 × 304

or

P = 610125.87 Pa

or

P = 610.125 kPa
