5 mole of oxygen are heated at constant ...

5 mole of oxygen are heated at constant volume from `10^(@)C` to `20^(@)C`. What will be the change in the internal energy of gas? The molar heat capacity of oxygen at constant pressure, `C_(P)=7.03calmol^(-1)k^(-1)` and `R=2calmol^(-1)k^(-1)`

Text Solution

AI Generated Solution

To find the change in internal energy of the gas, we can follow these steps: ### Step 1: Calculate the Molar Heat Capacity at Constant Volume (Cv) We know the relationship between the molar heat capacities at constant pressure (Cp) and constant volume (Cv): \[ C_p - C_v = R \] Given: - \( C_p = 7.03 \, \text{cal/mol·K} \) ...
