- Define the system to be an ice cube. If the ice cube melts into water, did the system have a positive or negative entropy change?For a power cycle operating as shown in the figure, Wcycle = 800 Btu and Qout = 1800 Btu. Hot body System Cold body Cout W cycle-in-out What is the heat input, Qin, in Btu, and what is the cycle thermal efficiency?. A rigid container (0.066 m3) is filled with an ideal gas (Cv = 2.5R) at 501K and 1.1 bar. Calculate the entropy changes asked in below. When an axial mixer is installed in a container and 15,000 J of work is applied to the gas under the insulation process, what is the entropy change of the gas?

Explain why they are isentropic.Topic: Thermodyamics (also included in Chem). Please explain what the Carnot cycle or a heat engine is about step by step.An object can have its entropy decrease only if... O heat flows into the object. O work is done on the object. O There is no way for an object have its entropy decrease. O something else has its entropy increase by at least as much.
