Which statement accurately describes test tubes and beakers

Question

Test tubes are better for transmitting liquids than beakers
Beakers have liquid volume (ml) markings on the side of them test tubes are unmarked
Beakers and test tubes both have round bottoms
Beakers can be held over flame test tubes cannot

Answer 1

The most accurate statement among the options provided is:

Beakers have liquid volume (ml) markings on the side of them; test tubes are unmarked.

Here's a brief explanation regarding the other statements:

1. Test tubes are better for transmitting liquids than beakers: This is not accurate as beakers are designed for pouring and transferring liquids more effectively than test tubes.

2. Beakers and test tubes both have round bottoms: This is often untrue; while beakers usually have flat bottoms, test tubes typically have cylindrical shapes with round bottoms.

3. Beakers can be held over flame; test tubes cannot: This statement is misleading. While beakers can be used over a flame, test tubes can also be used over flames in certain contexts (e.g., in a Bunsen burner setup), but caution must be taken depending on the material of the test tube.

Therefore, the clearest and most accurate statement is the one about the volume markings.
