Question

The isothermal bulk modulus of a gas at atmospheric pressure is
A) 1 mm of Hg B) 13.6 mm of Hg C) 1.013 x 10⁵ N/m²
D) 2.026 x 10⁵N/m²​

Answer 1

For isothermal process Bulk modulus = Pressure now at 1 atm ° 1.013 x 10^5 N/m² = 760 mm of Hg

Option 3

Answer 2

Answer:

C) 1.013 x 10⁵ N/m²

The value of isothermal bulk modulus of gas at one atmospheric pressure is equal to atmospheric pressure.
