- Under which condition does the combined entropy of two interacting systems decrease? Group of answer choices When there is no heat flow (meaning the two systems are isolated) When there is no work done When there is no change in internal energy NeverDefine the system to be an ice cube. If the ice cube melts into water, did the system have a positive or negative entropy change?please do D and E
- Refer to pictureAny help with doublechecking my work would be great!Which statement regarding entropy is false? A child builds a tower from a pile of blocks. The entropy of the blocks increases. A layer of salt then a layer of pepper are placed in a jar then shaken. The entropy of the salt and pepper increases. Gasoline is burned in a car engine to form exhaust. The entropy of the gasoline increases. A candle burns to heat the surrounding air. The entropy of the candle and surrounding air increases.
