Task3

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

Principles of Chemical Engineering – First Year 10. A solution in water contains 1.704 kg of HNO3/kg H;0, and the solution has a specific gravity of 1.382 at 20°C. What is the mass of HNO; in kg per cubic meter of solution at 20°C? Lecture: 3

Problem 03.028 - DEPENDENT MULTIPART PROBLEM - ASSIGN ALL PARTS NOTE: This is a multi-part question. Once an answer is submitted, you willI be unable to return to this part. A 1.9-m3 rigid tank contains steam at 220°C. One-third of the volume is in the liquid phase and the rest is in the vapor form. The properties of steam at 220°C are given as follows: vf= 0.001190 m3/kg and vg= 0.08609 m3/kg. Steam Vm3 220°C Problem 03.028.b - Quality of a saturated mixture Determine the quality of the saturated mixture. (You must provide an answer before moving to the next part) The quality of the saturated mixture is

### To make a conclusion for a report of an experiment on rockets, in which the openrocket software was used for the construction and modeling of two rockets: one one-stage and one two-stage. First rocket (single-stage) reached a maximum vertical speed of 200 m/s and a maximum height of 1000 m The second rocket (two-stage) reached a maximum vertical speed of 250 m/s and a maximum height of 1800 m To make a simplified conclusion, taking into account the efficiency of the software in the study of rockets

please read everything properly... Take 3 4 5 hrs but solve full accurate drawing on bond paper don't use chat gpt etc okk

*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

Problems 1. A database lists an equation for Û as Û= 1.10+ 0.8107+4.75 × 1047² where Û is in kilojoules per kilogram and 7 is in degrees Celsius. What are (a) the corresponding equation for Cv and (b) the reference temperature for Û? 2. Use the steam tables to calculate the change in internal energy between liquid water at 1000 kPa and 450 K, and steam at 3000 kPa and 800 K. How did you take into account the phase change in the water?
