Answer:

Correct option is A)

At sea level, the pressure is 1 atm. It drops to 0.65 atm.

The diameter is 0.2 m. The radius will be 0.1 m. It changes to x m.

For an ideal gas PV=nRT

Hence, at constant temperature, PV is constant.

PV=P

x=0.1154

2x=0.2308m

Thus, the diameter changes to 0.2308 m
