An ideal gas is expanding such as P T 2 = c o n s t a n t . The coefficient of volume expansion of the gas is
Options
- A1 T
- B2 T
- C3 T
- D4 T
Correct answer
C. 3 T
Step-by-step solution
P T 2 = c o n s t a n t n R T V T 2 = n R T 3 V - 1 = constant Differentiating the equation, we get 3 n R V T 2 d T - n R T 3 d V V 2 = 0 ⇒ γ = 1 V d V d T = 3 T
