In an Adiabatic Process (One in Which No Heat Transfer $p^{5} V^{7}=C$

question 153

Multiple Choice

In an adiabatic process (one in which no heat transfer takes place) , the pressure P and volume V of an ideal gas such as oxygen satisfy the equation $p^{5} V^{7}=C$ , where C is a constant. Suppose that at a certain instant of time, the volume of the gas is 2L, the pressure is 100 kPa, and the pressure is decreasing at the rate of 5 kPa/sec. Find the rate at which the volume is changing.

• A) 14 L/sec
• B) \(C-\) 14 L/sec
• C) \(C-\) \(\frac{1}{14}\) L/sec
• D) \(\frac{1}{14}\) L/sec
