Glass membranes have a pore size range between_________ 0.3 nm to 1000 nm. 0.1nm to 100 nm. 0.3 mm to 1000 mm. None of the above

To accurately answer the question regarding the pore size range of glass membranes, let’s examine the provided options:

1. 0.3 nm to 1000 nm
2. 0.1 nm to 100 nm
3. 0.3 mm to 1000 mm
4. None of the above

Analysis of the Options

• Glass membranes are typically characterized by their porous structure, which is often utilized in filtration and separation processes.
• The common pore size range for glass membranes generally falls within the nanometer scale.

Verifying the Correct Range:

1. Pore sizes from 0.3 nm to 1000 nm (Option 1): This range includes nanoporous materials and is plausible as a characteristic of a wide range of glass membranes.

2. Pore sizes from 0.1 nm to 100 nm (Option 2): This range is quite limited and does not encompass the broader range that certain types of glass membranes may exhibit.

3. Pore sizes from 0.3 mm to 1000 mm (Option 3): This is implausible as glass membranes do not typically have such large pore sizes.

4. None of the above: This would only apply if none of the provided ranges were correct.

Conclusion

Given the standard characteristics of glass membranes, the most accurate pore size range is:

Final Answer: 0.3 nm to 1000 nm (Option 1)
