Question

Which of the following temperatures corresponds to the freezing point of water? a) \(0 \mathrm{~K}\) b) \(0^{\circ} \mathrm{C}\) c) \(100^{\circ} \mathrm{C}\) d) \(100 \mathrm{~K}\) e) \(100^{\circ} \mathrm{F}\)

Short answer

Answer: The freezing point of water in Celsius is \(0^{\circ} \mathrm{C}\).

Step-by-step solution

Analyze each option

To find the correct answer, let's go through each option and determine if it corresponds to the freezing point of water.

Evaluate Option a)

Option a) states that the freezing point of water is \(0 \mathrm{~K}\). The Kelvin temperature scale has absolute zero (zero Kelvin) as the lowest possible temperature. At this temperature, all molecular motion stops. However, this does not correspond to the freezing point of water.

Evaluate Option b)

Option b) states that the freezing point of water is \(0^{\circ} \mathrm{C}\). The Celsius temperature scale is used to measure temperatures in most parts of the world, with its zero point set at the freezing point of water. This answer seems to be the correct one.

Evaluate Option c)

Option c) states that the freezing point of water is \(100^{\circ} \mathrm{C}\). This temperature corresponds to the boiling point of water, not the freezing point, on the Celsius scale. So this option is incorrect.

Evaluate Option d)

Option d) states that the freezing point of water is \(100 \mathrm{~K}\). In the Kelvin scale, the freezing point of water is actually at 273.15 K. So this option is incorrect as well.

Evaluate Option e)

Option e) states that the freezing point of water is \(100^{\circ} \mathrm{F}\). In the Fahrenheit scale, the freezing point of water is at 32 degrees, not 100 degrees. So this option is incorrect too.

Choose the correct answer

According to our analysis, option b) \(0^{\circ} \mathrm{C}\) corresponds to the freezing point of water. Therefore, the correct answer is option b.
