1
0.50 mol contains 3.01107038 × 10^23 specified entities because the Avogadro constant is exact.
2
A falling object trades gravitational potential energy for kinetic energy; total energy is conserved when losses are accounted for.
3
At fixed volume and amount, doubling absolute temperature in the ideal model doubles pressure.
具体的な確認点
A scientific number is never just digits: it represents a quantity, a unit, a definition or measurement, and often an uncertainty. Good science keeps those pieces visible.
