Suppose that the average speed (vm) of carbon dioxide molecules (molar mass 44.0 g/mol) in a flame is found to be 2.16 x 105 m/s. What temperature does this represent?

One mole of hydrogen gas (molar mass = 2.0 g/mol) has an rms velocity of 2.0 x 10° m/s. To what temperature on the Celsius scale does this correspond? 3.2 x 105 °C O 4.8 x 104 C 3.2 x 102 °C 48°C 6.9°C

A hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be? SOMEONE PLEASE HELP ME!!

Chapter 14, Problem 44 A cubical box with sides of length 0.342 m contains 1.220 moles of neon gas at a temperature of 319 K. What is the average rate (in atoms/s) at which neon atoms collide with one side of the container? The mass of a single neon atom is 3.35x10-26 kg.

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%

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 weather balloon is designed to expand to a maximum radius of 15.6 m when in flight at its working altitude, where the air pressure is 0.0282 atm and the temperature is −65∘−65∘C. If the balloon is filled at 0.873 atm and 21∘∘C, what is its radius at lift-off?

Two students in a physics lab have to construct a constant-volume gas thermometer as part of their end of year project. They use liquid nitrogen (-196°C) and boiling pentane (36.1°C) to calibrate the thermometer. The corresponding values of pressure are 0.420 atm and 1.325 atm. The students plot a pressure versus temperature graph with pressure on the y-axis and temperature on the x-axis. (a) Determine the y intercept and slope of the linear graph that relates the pressure to the temperature. slope     atm/°C y intercept     atm b) What value of absolute zero do the students get from this calibration?°C(c) What pressure readings would this thermometer give for the freezing and boiling points of water? freezing point     atm boiling point     atm

Before leaving on a trip to Melbourne Beach, Florida, you measure the pressure inside the tires of your car at a gas station. At – 7.5 C (chilly!), the tire pressure is 206.5 kPa. When you arrive in Florida, you check the tire pressure and find it is now 236.5 kPa. What is the temperature in Melbourne Beach?
