Question

1. what temperature (°c) does water have its greatest density (check your density slides)? 13. if an object sinks in water, what would you know about its density?

Explanation:

Step1: Recall water - density property

Water has its maximum density at 4°C due to the anomalous expansion of water.

Step2: Recall density - sinking relation

An object sinks in water if its density is greater than the density of water.

Answer:

1. 4
2. Its density is greater than the density of water.
