✔ 最佳答案

PV=nRT
1000P=nR(100)
P=0.1nR
after it cool down,T=20,since the can found collapsed,
it means pressure =atmospheric pressure,which is remain unchange
PV=nRT
V=nR(20)/P=nR(20)/[0.1nR]=200(cm^3)

If atmospheric pressure is 10^5 Pa,since the can found collapsed,
it means pressure =atmospheric pressure=10^5 Pa
