 1 The Volume of 10 mols of a gas at a pressure of atm is 200 L(liters). What is its temperature in kelvin to the nearest degree? 2 What is the pressure to the nearest N/m^2 of 2 mols of a Gas with a volume of 540 L(liters) and a temperature of kelvin? 3 A gas bubble with an initial volume of 7 milliliters rises from a depth of meters.If the temperature does not change, what is its volume, to the nearest ml, when it reaches the surface(density of water=1000 kg/m^3)? 4 If the temperature in Celsius is , what is the temperature(to the nearest degree) in kelvin? 5 If the temperature in Celsius is , what is the temperature(to the nearest degree) in Fahrenheit? 6 Concrete sidewalk slabs 8 meters long at 0 degrees Celsius are to be exposed to a temperature range from 0 to degrees Celsius. How wide (to the nearest mm) should the cracks be? 7 A tire is inflated to a gauge pressure of 2.0 atm with air at a temperature of 15 degrees Celsius. If the tire warms to Celsius, what fraction (to the nearest hundredth of a decimal point) of the air must be removed to return to the original pressure? 8 What is the average kinetic energy in eV (electron volts) to three decimal digits of Nitrogen molecules, at a temperature of degrees Celsius ? 9 What is the root-mean-square velocity (to the nearest m/s) of the molecules in problem 8? (The mass of a Nitrogen molecule is 46.5*10^-27 kg) 10 Six molecules have the following speeds (in arbitrary units): , , , , , .What is their rms speed (to the nearest single decimal digit.)?
