An open system is a system in which both heat and mass are escaping/coming in. (Think of a glass of water; water is evaporating and heat is melting the ice). A closed system is when only heat is escaping/coming in (A bottle of water where water vapor can't escape, but it can still be warmed) An isolated system occurs when neither heat nor mass can escape/come in (Think of a thermos; neither heat nor vapor can escape). Hope this helps!

Which of the following is a chemical change?
FromTheMoon [43]

<u>Answer:</u>

<em>Silver tarnishing as the silver metal reacts with sulphur is a chemical change.</em>

<u>Explanation:</u>

Tarnishing is the process of chemical change occurring on the surface of objects leading to corrosion or other defects on the surface. The remaining options like dilution, eroding is a physical change where the concentration of salt and rock particles will be decreased, respectively.

Similarly for soil drying also the concentration of water will be decreased leading to a physical change from wetty or dry soil.

But the last option which indicates tarnishing of silver metal on reaction with sulphur is a chemical process as the surface of silver metal will be reacting to sulphur and leads to lose of electrons which leads to corrosion of the surface or tarnishing of silver.
