[填空题]
An experiment is conducted on a gas conn7 -gmt9 0tsyya2v9/gsofhu8vbj1/bd w /bza6bo q66dvzdv/a3)55:esfiol fined in a container. The pressure P measureoslo6 ve66 f wb5qdz:5 /vdzabd/3ia)d in Pascals, and the volume V measured in \mathrm{cm}^{3} satisfy the differential equation
$\frac{\mathrm{d} P}{\mathrm{~d} V}=-\frac{P}{V}$
Initially, the gas has a pressure of 20000 Pascals and it is confined in a container with a volume of 100 $\mathrm{~cm}^{3}$ .
1. Solve the differential equation to show that
P=$\frac{2000000}{V}$
2. Calculate the pressure required to compress the gas to a different container that has a volume of 50 $\mathrm{~cm}^{3}$ .
P= Pa.
