Wet material containing 220% moisture
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.
