0.64 g of oxygen is kept ini a rigid container and is heated. Find the amount of heat required to raise the temperature from `20^(@)` to `30^(@)` C. The molar heat capacity of oxygen at constant volume is `20JK^(-1)mol^(-1)`

Explanation

To solve the problem of finding the amount of heat required to raise the temperature of 0.64 g of oxygen from 20°C to 30°C, we can follow these steps:

### Step 1: Identify the given data
- Mass of oxygen (m) = 0.64 g
- Initial temperature (T1) = 20°C
- Final temperature (T2) = 30°C
- Molar heat capacity of oxygen at constant volume (Cv) = 20 J/(K·mol)
