sealed container has a volume of 0.020 m3 and contains 15.0 g of molecular nitrogen (N2),which has a molecular mass of 28.0 u. The gas is at 525 K. What is the absolute pressure of thenitrogen gas?A) 3.9 × 10–19 PaB) 4.3 × 10–5 PaC) 1.2 × 105 PaD) 1.9 × 105 PaE) 4.3 × 106 Pa

It is known that 28 g of a certain ideal gas occupy 26.4 liters at standard conditions (0° C, 1 atm). The volume occupied by 42 g of this gas at standard conditions (in liters) is: a. 22.4 b. 14.9 c. 33.4 d. more data are needed e. 39.6

7. Containers A and B in the figure to the right hold the same gas. The volume of B is four times the volume of A. The two containers are connected by a thin tube (negligible volume) and a valve that is closed. The gas in A is at 300 K and pressure of 1.0 × 10³ Pa. The gas in B is at 400 K and pressure of 5.0 × 105 Pa. Heaters will maintain the temperatures of A and B even after the valve is opened A 300 K Valve B 400 K a) After the valve is opened, gas will flow one way or the other until A and B have equal pressure. What is the final pressure? b) Is this a reversible or an irreversible process? Explain..

The volume of a gas at 20°C is 100cm3 at normal pressure. If it is heated to 100°C, its volume becomes 125cm3 at the same pressure, then volume coefficients of the gas (at normal pressure) is? a) 0.0033/°C b) 0.0025/°C c) 0.0030/°C d) 0.0021/°C
