Question

Explain the difference between a physical and a chemical property. Give at least 2 examples of each type of property. Chemistry seeks to explain both the physical and chemical properties of matter.

Answer 1

Answer:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed. $H_2+\frac{1}{2}O_2\rightarrow H_2O$

Example: 1. reactivity of substances

2. Toxicity of substances

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc. $H_2O(s)\rightarrow H_2O(l)$

Example: 1. Melting Point

2. Density
