3 moles of gas of an ideal gas have a volume of 0.026 m3 and a pressure of 300 kpa. What is the temperature in degrees Celsius? (Step 1 identify the data. Step 2 pose the formula. Step 3 exercise.)

A large cylindrical tank contains 0.760 m3 of nitrogen gas at 20.0 ∘C and 1.45×105 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.410 m3 and the temperature is increased to 159 ∘C? Express your answer in pascals.

If 23.5 moles of an ideal gas occupies 0.0465 cubic meters at 14.5 °C, what is the pressure of the gas? pressure: Pa

A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).

A gas under constant pressure has a volume of 30.57m^3 and a temperature of 59.0 K. A change in temperature caused the volume to change to 121.14m^3. Based on the relationship between volume and temperature, what must have happened to the temperature? A- Temperature decreased B- Temperature increased C- Temperature stayed the same D- Temperature trend can not be determined

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.

An ideal gas at 7°C is in a spherical flexible container having a radius of 1.04 cm. The gas is heated at constant pressure to 88°C. Determine the radius of the spherical container after the gas is heated. [Volume of a sphere = (4/3)?r3.]

Large helium-filled balloons are used to lift scientific equipment to high altitudes. (a)What is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 24.8°C and rises to an altitude where its volume is sixteen times the original volume and its temperature is  −41.7°C?  (Enter your answer to at least 3 decimal places) _______________ atm   (b)What is the gauge pressure? (Enter your answer in atm and to at least 3 decimal places. Assume atmospheric pressure is constant.) ________________ atm

The density of lead is 1.13 x 104 kg/m3 at 20.0°C. Find its density (in kg/m3) at 128°C. (Use a = 29 x 10-6 (°C)-1 for the coefficient of linear expansion. Give your answer to at least four significant figures.) HINT kg/m3
