\textbf{197.} The volume of an ideal gas (complete) at temperature $47°C$ is $2$ liters and its pressure is $2\times10^5\,\text{Pa}$. First, at constant pressure the temperature of the gas increases, and then at constant volume the volume of the gas decreases by $20$ percent. What is the final pressure of the gas in Pascals?
