Discuss why the temperature of a substance remains relatively constant during the freezing of liquid to solid. Explain why water spontaneously freezes to form ice below 0 degree C even though the entropy of the water decreases during the s...
A few grams of water vapor condenses to a liquid at a constant temperature of -1.0 degrees Celsius. Will the entropy of the system increase, decrease, or stay the same? Explain. When liquid water freezes: a. both the energy and entropy decrease. b. both the ...
For the last 150 years or so, virtually every car has run on a liquid we rather confusingly call gas. But in the next 150 years, many people think cars will run on a real gas: hydrogen. In theory, running cars off hydrogen is a great idea: it's the simplest and most common ...
