A 0.0303-m container is initially evacuated. Then, 5.71 g of water is placed in the container, and, after some time, all of the water evaporates. If the temperature of the water vapor is 448 K, what is its pressure? Number Units

A gas condensed in a cylinder with a nozzle is initially at p_1=2000 Pa, V_1= 2.0 l, and t_1=300 K. a) If the volume decreases to 0.50 L while the temperature remains low, what is the new pressure?b) If in a) the temperature increases to 400 K when the volume changes, what will be the new pressure?

An ideal gas is enclosed in a constant volume container at a pressure of 0.7atm and an initial temperature of 100°C. The pressure is then decreased to .512atm with a temperature of 37°C. If the pressure is then decreased again to .34atm. What is the final temperature?

Suppose that the rms speed of carbon dioxide molecules, with molar mass of 44.0 g/mol, in a flame is found to be 1.2 × 105 m/s a.What temperature, in kelvins, does this represent?  b. What temperature, in celsius does this represent?

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
