Question

Why do you think a small tube was used to observe the expansion of water?

Answer 1

Step-by-step explanation:

glass has a melting point of 1400 to 1600 degrees celsius, and water has a boiling point of 100 degrees celsius, if you were to boil something under 1400 to 1600 degrees celsius, then it wouldnt do a thing to the glass.

Answer 2

Answer: The tube is narrow so that a small change in volume will result in a considerable change in height.
