Given diameter (D) = 25 cm = 0.25 m
Height (H) = 80 cm = 0.8 m
∴ Volume of the cylinder (V) = \(\frac{πD^2}4 \times H\)
= 0.03927 m3
Gas pressure (p) = 12 MPa = 12000 kPa
Temperature (T) = 27º C = 300 K
(a) Mass of gas filled in the cylinder
(b) In cooking gas main component is ethen and it filled in 18 bar pressure. At that pressure it is not a gas it is liquid form in atmospheric temperature so its weight is amount 14 kg.
(c) Let temperature be T K, then pressure, p = 15 MPa = 15000 kPa
