For a particular gas `gamma = (5)/(3)`and is heated at constant pressure. Calculate the percentage of total heat supplied, used for external work.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the relationship between heat supplied and work done at constant pressure.
At constant pressure, the heat supplied (dq) to the gas can be expressed as:
\[ dq = nC_p \Delta T \]
where \( n \) is the number of moles, \( C_p \) is the specific heat at constant pressure, and \( \Delta T \) is the change in temperature.

### Step 2: Express the work done in terms of pressure and volume change.
