100 g of water at 20 degree centigrade is mixed with 100 g of water at 5 degree centegrade the temperature of mixture will be?
15 degree centigrade
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 salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
Entropy will decrease.
What has the greatest entropy per mole ice water or steam?
Steam will have the greatest entropy
Boiling point of water is 100 degree celsius but why it boils at 130?
The presence of some impurities and dissolved salts increases the boiling point of water from 100 degree celsius.
Is entropy of water is higher than entropy of ice?
Entropy of water is higher than ice due randomness in the water molecule
What is the definition of entropy?
The entropy of the gas was too high. It means the degree of randomness in gas was very large.
How does the entropy of a system change for condensation of water?
The entropy is lower.
100 g of water at 20 degree centigrade is mixed with 100 g of water at 5 degree centegrade the temperature of mixture will be?
15 degree centigrade
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 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.
What is the point of water at 100 degree Celsius?
Water boils at 100 degrees Celsius

Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
Entropy will decrease.
Is water vaporizing entropy?
The transition of water (or of anything) from the liquid phase to the gas phase does constitute an increase in entropy.
What has the greatest entropy per mole ice water or steam?
Steam will have the greatest entropy
