Question

the following supplies available:

• three glass bottles
• olive oil
• vegetable oil
• vinegar
• cold water
• salt

using only these supplies, which two questions can cody investigate with an experiment?

• does vegetable oil or olive oil separate faster when mixed with water?
• does vegetable oil separate faster when stirred together with cold water or with hot water?
• does vegetable oil separate faster when stirred together with vinegar or with water?
• does vinegar separate faster when stirred together with olive oil or with coconut oil?

Explanation:

• For "Does vegetable oil or olive oil separate faster when mixed with water?": The supplies include vegetable oil, olive oil, and water, so we can test the separation speed of these two oils with water.
• For "Does vegetable oil separate faster when stirred together with vinegar or with water?": The supplies have vegetable oil, vinegar, and water, allowing us to compare the separation speed of vegetable oil with vinegar and with water. The second option in the original (about hot water) is invalid as hot water isn't a supply, and the fourth option is invalid as coconut oil isn't available.

Answer:

1. Does vegetable oil or olive oil separate faster when mixed with water?
2. Does vegetable oil separate faster when stirred together with vinegar or with water?
