Question

Ideal gas for which 'ϒ' = 1.5 is suddenly compressed to `1/4`th of its initial volume. The ratio of 4 the final pressure to the initial pressure is ______.

 `(ϒ = "C"_"p"/"C"_"v")`

विकल्प

• 4: 1

• 8: 1

• 1: 16

• 1: 18

Answer 1

Ideal gas for which 'ϒ' = 1.5 is suddenly compressed to `1/4`th of its initial volume. The ratio of 4 the final pressure to the initial pressure is 8:1.

Explanation:

For adiabatic process

`"P"_1"V"_1^ϒ = "P"_2 "V"_2^ϒ`

` therefore "P"_2/"P"_2 = ("V"_1/"V"_2)^ϒ = (4)^(3/2 = 8`
