Important points from the story

The cup of tea had to contain ⅔ boiling water, ⅓ cold milk, and be well stirred. She even invested in a special cup that had lines marking the exact volumes of the water and the milk.

Ruth filled her teacup ⅔ of the way with boiling water, but the phone rang before she had time to pour the milk.

Ruth knew that the call was about a lengthy one, and would take at least 10 minutes.

What should Ruth do?

Proposal 1: Quickly pour the milk and stir well. Then drink the tea after the conversation.

Proposal 2: Leave the cup with the hot water on the table, return the milk to the refrigerator, talk to Dr. Johnson, and pour the cold milk immediately after the conversation.

Abdul says proposal 3: don’t drink at all.
Redo the tea after the call.

A serious answer

janice192 — 2023-11-15 07:11:02 UTC

Proposal 1 would be preferred. If we were to put the milk back in the fridge, it will be of a lower temperature when you make the tea it will also be colder.

Firm Decision

Research Question

suhaila_abdullah — 2023-11-15 07:25:52 UTC

To find out if mixing the milk and tea immediately or 10 minutes later would make the tea lose heat slower

Protocol

janice192 — 2023-11-15 07:27:54 UTC

Pour 100ml of boiling water into the beaker.
Add the tea bags into the beakers
In beaker A, pour 50ml of cold milk immediately.
Place the laboratory thermometers in both beakers
Measure and record the temperatures every minute
Add 50ml of cold milk to beaker B at the 10 minute mark.
Continue to record the temperatures in both beakers for another 5 minutes.
