As the temperature of the nitrogen gas increases _______________ of same gas increases. Viscosity Specific volume Weight density Density

Part A Some tire stores claim that filling your car tires with pure, dry nitrogen is much better than using plain air. They make the following claims. 1. The pressure inside N₂-filled tires does not rise or fall with temperature changes. 2. Nitrogen leaks out of tires much more slowly than air because the N₂ molecules are bigger. 3. Nitrogen is not very reactive, and moisture and O₂ in air cause corrosion that shortens tire life by 25-30% Evaluate the claim as a whole. Check all that apply. Claim passes falsifiability test. Claim passes logic test. Claim passes replicability test. Claim passes sufficiency test Claim fails all four FLaReS tests. Submit Request Answer

While discussing friction in matter: Technician A says that friction creates heat. Technician B says that friction only occurs with solids and is not present with liquids and gases. Who is correct? Technician A only Technician B only Both A and B Neither A nor B

How would density be used to determine the concentration of antifreeze in the cooling system of an automobile?

Use Table 31-6 to determine what would be the pressures in cylinders containing: (a) MAPP , (b) propane, and (c) ethane on a 100F(38C) day.

*29. ssm The drawing refers to one mole of a monatomic ideal gas and shows a process that has four steps, two isobaric (A to B, C to D) and two isochoric (B to C, D to A). Complete the following table by calculating AU, W, and Q (including the algebraic signs) for each of the four steps. B -800.0-K isotherm -400.0-K isotherm 200.0-K isotherm D Volume Pressure
