What temperature, in celsius does this represent?2.40 moles of an ideal gas is initially at 40.0 oC and 1.35 atm. a) What is its volume under these conditions?b) If it is then compressed to one third of its initial volume and its pressure increases to 2.0 atm, what, in Centigrade degrees, will be its temperature?
- 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.1.68 L of helium gas in a balloon at room temperature (25 °C) was put in an oven at 250 °C and allowed to come to thermal equilibrium with its new surroundings. a) Calculate AU, AH, w and q for the gas inside the balloon.
