Question 302: Thermodynamics & KTG

Question

An ideal gas is expanding such that PT
3
= constant. The coefficient of volume expansion of the gas is :

Accepted Answer

PT
3
= constant
$$\left( {{{nRT} \over v}} \right)$$T
3
= constant
T
4
V
$$-$$1
= constant
T
4
= kV
$$ \Rightarrow 4{{\Delta T} \over T} = {{\Delta V} \over V}$$ ....... (1)
$$\Delta$$V = V$$\gamma$$$$\Delta$$T ........ (2)
comparing (1) and (2), we get
$$\gamma  = {4 \over T}$$

Answer

$${1 \over T}$$

Answer

$${2 \over T}$$

Answer

$${4 \over T}$$

Answer

$${3 \over T}$$
