1. What will happen to a hard-boiled egg if placed in a beaker of saltwater?

Answer: B

Explanation:

A hard-boiled egg will shrivel due to water leaving the egg when placed in a beaker of saltwater.

When a hard-boiled egg is placed in saltwater, the high concentration of salt outside the egg creates a hypertonic environment. This causes water to move out of the egg, leading it to shrivel.

A) Expand due to water moving into the egg

This option is incorrect because the saltwater is hypertonic compared to the inside of the egg. Instead of water moving into the egg, the opposite occurs, resulting in the egg losing water.

B) Shrivel due to water leaving the egg

This option is correct as it accurately describes the process of osmosis in a hypertonic solution. The concentration of solutes outside the egg is greater, causing water to exit the egg and leading to its shriveling.

C) Remain the same

This option is also incorrect because the egg will not remain unchanged. The osmotic pressure difference between the egg and the saltwater will cause significant movement of water out of the egg, altering its state.

D) None of the above

This option is incorrect as well because option B provides the correct outcome. The egg will indeed shrivel, disproving the notion that none of the provided options are correct.

Conclusion

In conclusion, the correct answer is B, as placing a hard-boiled egg in saltwater leads to water leaving the egg, resulting in shriveling. Options A and C do not accurately reflect the osmotic process, and option D is invalid since one of the options (B) is indeed correct.
