A sealed container holds an ideal gas at an initial pressure of \(1.0\ \text{atm}\) and a volume of \(2.0\ \text{L}\). After heating, the pressure rises to \(2.5\ \text{atm}\) while the volume expands to \(3.0\ \text{L}\), and the temperature becomes \(350\ \text{K}\). Assuming the amount of gas remains constant, calculate the initial temperature of the gas in degrees Celsius.
