Answer 1

Answer #1

IP(kPa) 300 290 270 kPa vs L 250 220 2001 y = 48.306x2 - 246.01x +498.77

trendline graph equation:

y = 48.306*x² -246.01*x + 498.77

y axis - P

x axis- V

At initial volume V = 1L

P1 = 301.066

At final volume V = 2 L

P2 = 199.974

P1 = 301.066

P2 = 199.974

Area under the given curve = P1 - P2 = 301.066 - 199.974 = 101.092 kPa.L = 101.092 Pa. m3

Work done by gas expansion process = Area under the curve = 101.092 J
