Answer: 3. H2O(l) -> H2O(g)
Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.
The metric system of units is known as the International System of Units (ISU).
Answer:
Gas B
Explanation:
diffusion/effusion increases when:
- Temperature increases
- A gas has lower molar mass
- Particles are moving quickly
diffusion/effusion decreases when:
- Temperature decreases
- A gas has higher molar mass
- Particles are moving slowly
Hence: since gas B has the lowest molar mass, it has the highest rate of effusion
I also took the test so I know it is right
