The entropy of water at 100 degrees Celsius (373.15 K) is approximately entropy can vary depending on pressure and phase. For liquid water at this temperature and standard pressure (1 atm), the molar entropy is about 70 J/(mol·K). If considering water in its gaseous state (steam) at the same temperature, the entropy is much higher, around 188 J/(mol·K).
What else can I help you with?
What has the greatest entropy per mole ice water or steam?
Steam has the greatest entropy per mole compared to ice and water, as steam has a higher degree of disorder and randomness in its molecular arrangement.
Is Entropy proportional to temperature and pressure?
No. The calculation of entropy is more complicated than that. For example: to increase the temperature of 1 g of water by 1 degree (kelvin or celsius), you need about 4.2 joule. Now, if you increase the temperature of water from 273K (freezing point) to 373K (boiling point), for the first degree the entropy increases by approximately 4.2 joule / 273K = 0.0154 J/K. But for the last degree of increase, from 372 to 373K, the entropy increases by 4.2 joule / 372 kelvin = 0.0113 J/K. To calculate the increase in entropy, the entire range of temperatures must be divided into small intervals (in practice, there are shortcuts for the calculation). So, you see the relationship is not quite as simple as a simple proportion.
When water becomes ice the entropy decreases does this contradict the second law?
No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.
Which form of water has the highest entropy?
Water vapor has the highest entropy compared to liquid water and ice because gas molecules have more freedom of movement and therefore more possible microstates, resulting in higher entropy.
What form of water has the lowest entropy?
The form of water with the lowest entropy is ice, specifically at absolute zero temperature (0 Kelvin). In this state, the water molecules are arranged in a highly ordered crystalline structure, resulting in minimal molecular motion and the lowest possible entropy. As temperature increases, the entropy of water increases due to the greater disorder in liquid water and, even more so, in water vapor.
What has the greatest entropy per mole ice water or steam?
Steam has the greatest entropy per mole compared to ice and water, as steam has a higher degree of disorder and randomness in its molecular arrangement.
Is entropy of water is higher than entropy of ice?
Yes, the entropy of water is higher than the entropy of ice because water is in a more disordered state compared to ice, which has a more ordered and structured arrangement of molecules. Entropy is a measure of disorder in a system, so the more disordered the state, the higher the entropy.
What is the physical state of water at 250 degree Celsius?
The boiling point of water is 100 degree celsius. Therefore water changes in to vapor after 100 degree celsius. Therefore the physical state of water at 250 degree celsius is "Gas".
What is the point of water at 100 degree Celsius?
Water boils at 100 degrees Celsius
Which of the following has the highest entropy Water Ice Water solution or Water vapor?
Water vapor has the highest entropy because gases generally have higher entropy compared to liquids or solids at the same temperature. Entropy tends to increase with the randomness or disorder of the molecules, so the highly disordered state of water vapor results in higher entropy.
Is Entropy proportional to temperature and pressure?
No. The calculation of entropy is more complicated than that. For example: to increase the temperature of 1 g of water by 1 degree (kelvin or celsius), you need about 4.2 joule. Now, if you increase the temperature of water from 273K (freezing point) to 373K (boiling point), for the first degree the entropy increases by approximately 4.2 joule / 273K = 0.0154 J/K.

What describes the phases of water Water expands as it changes from a solid to a liquid?
the entropy of water is higher than the entropy of ice.
How does the entropy of a system change for condensation of water?
The entropy of a system typically decreases during the condensation of water. This is because the molecules of water vapor become more ordered as they transition into the liquid state, reducing the overall disorder (entropy) in the system.
What happens at one hundred degrees Celsius?
At 100 degree celsius water starts boiling. It starts changing into water vapour. 100 degree celsius is the boiling point of water.
When water becomes ice the entropy decreases does this contradict the second law?
No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.
At what degree does the water boil?
100 degrees cel.
How do you increase temperature of boiling water?
100 degree
