ANSWER:
Step 1 of 5
Which of the following statements describe physical properties and which describe chemical properties
Physical property: Physical properties are the property of matter which does not change its composition. For example: texture, colour, order, melting point boiling point etc.
Chemical property: A property in which the chemical composition or identity of a substance has changed, is called as chemical property.
(a) Iron has a tendency to rust
The tendency of iron to change into rust is a chemical property. Because iron has changed its composition and identity when it turn into rust by combining with oxygen and water.
