I underlined the part I need help with it says, " V ↓ by __ %"
Transcribed Image Text:... A gas sample initially in 1.31 L at 298 K was cooled to 273 K
under constant P. Find its new volume:
1.31 L/298 K = V2/273 K
V2 =
273 K 1.31 L 1,2001 L

A gas sample initially in 0.56 cm3 at 25 °C was heated to take up
5.6 L under constant P. Find its new toc:
T = (25 + 273) K = 298 K
