An evacuated tank is filled with gas from a constant pressure line. Develop an expression relating the temperature of the gas in the tank to the temperature of the gas in the line. Assume the gas is ideal with constant heat capacities, and ignore heat transfer between the gas and the tank.

Final answer:

The temperature of the gas in the tank can be related to the temperature of the gas in the constant pressure line using the ideal gas law.

Step-by-step explanation:

The temperature of the gas in the tank can be related to the temperature of the gas in the constant pressure line using the ideal gas law. The ideal gas law states that for a given amount of gas at constant temperature and pressure, the product of the pressure and volume is a constant. Mathematically, this can be expressed as:

Ptank * Vtank = Pline * Vline

Where Ptank and Vtank are the pressure and volume of the gas in the tank, and Pline and Vline are the pressure and volume of the gas in the line. Since the pressure is constant in this case, the equation can be simplified to:

Vtank = Vline * (Ttank / Tline)

Where Vtank and Vline are the volumes of the gas in the tank and line, and Ttank and Tline are the temperatures of the gas in the tank and line, respectively. This expression relates the temperature of the gas in the tank to the temperature of the gas in the line.
