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.

109. Suit formation in diesel engine is due to
1) excess fuel during combustion
2) excess air during combustion
3) excess carbon during combustion
4) excess CO during combustion
A fuel has the following constituents: carbon 85%, hyrdogen 13%, oxygen 2%. When burning this fuel in a boiler furnace the air supply is 50% in excess. Calculate the actual air-fuel ratio.
