A Goodyear blimp typically contains 6800 m3 of helium (He) at an absolute pressure of 1.10 x 105 Pa. The temperature of the helium is 278 K. What is the mass (in kg) of the helium in the blimp?

n = 3.9 moles of an ideal gas are pumped into a chamber of volume V = 0.135 m3   Part (a)  The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas?        Part (b)  The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas

A Goodyear blimp typically contains 5300 m of helium (He) at an absolute pressure of 1.10 x 10 Pa. The temperature of the helium is 275 K. What is the mass (in kg) of the helium in the blimp? Number Units the tolerance is +/-2%

Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 131 K. The other gas is neon (Ne). What is the temperature of the neon?

The number density of gas atoms at a certain location in the space above our planet is about 0.75 × 10!1 m²³, and the pressure is 2.9 x 10- 10 Pa in this region. What is the temperature in this region, in degrees Celsius? T =

Twenty-five milliliters of liquid nitrogen (density = 0.807 g/mL) is poured into a cylindrical container with a radius of 10.9 cm and a length of 20.3 cm. The container initially contains only air at a pressure of 760.0 mmHg (atmospheric pressure) and a temperature of 298 K. If the liquid nitrogen completely vaporizes, what is the total force (in lb) on the interior of the container at 298 K ? ΜΕ ΑΣΦ ? F = lb

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.

Two massless, frictionless pistons are inside a horizontal tube opened at both ends. A 10-cm-long thread connects the pistons. The cross-sectional area of the tube is 20 cm2. The pressure and temperature of gas between the pistons and the outside air are the same and are equal to P = 1.0×10^5 N/m^2 and T = 21C. At what temperature will the thread break if it breaks when the tension reaches 32 N ?

Hydrogen gas is enclosed in a chamber at 200 degrees C and a volume of 0.0250 m3.  Initially, the pressure in the gas is 1.50 x 106 Pa.  The chamber is removed from the heat source and allowed to cool until the pressure in the gas falls to 0.950 x 106 Pa.  What is T2?

The mass of a hot-air balloon and its cargo (not including the air inside) is 160 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is 550 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0°C is 1.244 kg/m3.) K=??
