It is because an apple have some iron so when it is exposed into air the iron gets oxidised and turns reddish/ brown.
False. The apple DOES turn brown in reacting with oxygen- but it is a chemical change.
a chimical reaction
Chemical property
Yes, because if it doesn't change whatever the substance is, it's a physical property. For example, if you have a piece of paper, you can fold it in half. When you do that, it proves the piece of paper to be flexible without turning the paper into something else.
yes ice being cold is a physical property. but once that ice melts it will be a chemical property because it is turning into another sunstence (water)
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
i think it is chemical but it may be physical.
No, it's a chemical property

It is not a property it is the process of turning a liquid into a gas. The enthalpy change of evaporation would be a chemical property.

For better ability to turn and for faster travel
its a physical property of water. if u r more intersted in chemistry and wanna increase ur knowledge u should must visit: http://www.getgyan.com/resources/Presentations/Miscellaneous%20Technologies

Physical
Yes, evaporation is a physical change of phase.
