Water is considered to be unusual when compared to other substances with a similar molar mass (for example, carbon dioxide). Which of these properties would correctly illustrate this fact?
- Water has a very low melting point
compared to other substances.
- Water has a very low specific heat capacity
compared to other substances
- Water is a liquid at room temperature
while many similar substances are solids.
- Water has a very high heat of vaporization
compared to other substances.
- Water has a very low melting point
compared to other substances. - Water has a very low specific heat capacity
compared to other substances - Water is a liquid at room temperature
while many similar substances are solids. - Water has a very high heat of vaporization
compared to other substances.
1 Answer
The answer is 4. Water has a very high heat of vaporization compared to other substances.
Explanation:
Carbon dioxide is not a good comparison to water. Its molar mass is
Ammonia and methane are better comparisons, because they do have molar masses similar to that of water.
Water:
Molar mass:
Ammonia:
