Hey, good to see you again.
Here are the answers to your questions about water's volume and density at different temperatures:
Water exhibits an anomalous expansion, meaning its density is not highest at its freezing point. Instead, it reaches its maximum density at 4°C. Consequently, it occupies its minimum volume* at this temperature. As the temperature moves away from 4°C (either increasing or decreasing), water's density decreases and its volume increases.
1. At which of the following temperatures will a given mass of water occupy the greatest volume?
The greatest volume occurs at the temperature furthest from 4°C where expansion is most significant.
Answer:* 100°C
2. At which of the following temperatures will a given mass of water occupy the greatest density?
Water has its maximum density at 4°C.
Answer:* 4°C
3. At which of the following temperatures will a given mass of water occupy the lowest volume?
The lowest volume corresponds to the greatest density, which is at 4°C.
Answer:* 4°C
4. At which of the following temperatures will a given mass of water occupy the lowest density?
The lowest density corresponds to the greatest volume, which occurs at the highest temperature listed.
Answer:* 100°C
