Question

The amount of heat that must be supplied to 35 &#160; g of oxygen at room temperature to raise its temperature by 80 &#160; &#176; C at constant volume is (molecular mass of oxygen is 32 and R = 8 . 3 &#160; J &#160; mol - 1 &#160; K - 1 )

Aicharya · Accepted Answer

The expression for the heat supplied at constant volume,

$Q = n C_{v} d T$

$Q = \frac{m}{M} C_{ν} d T$

For oxygen, Specific heat at constant volume
$C_{v} = \frac{f}{2} R T = \frac{5}{2} R T$ ( $f =$ Degree of freedom)

Substitute the given values in the above equation.

$Q = \frac{35}{32} (\frac{5}{2} R) (80)$

$Q = \frac{35}{32} (\frac{5}{2} \times 8.31) (80)$

$Q = 1817.812 J$

$Q \approx 1.81 kJ$
