Answer #1

Answer-

Important point---

1--Physical property of substance are those property which can be obtained without any chemical reaction in substance or those property which can be obtained without changing identity

2-Chemical property are those property which can be obtained only after chemical reaction in substance.

Here, Colour, hardness, density, and conductivity are physical property because for obtaning them no need to cause chemical reaction in substance.

Flammability and reactivity with other substance are chemical property because they can't obtained without chemical reaction in substance

The National Institute of Standards and Technology (NIST) supplies "standard materials" whose physical properties are supposed to be known. For example, you can buy from NIST a liquid whose electrical conductivity is supposed to be 5. (The units for conductivity are microsiemens per centimeter. Distilled water has conductivity 0.5.) Of course, no measurement is exactly correct. NIST knows the variability of its measurements very well, so it is quite realistic to assume that the population of all measurements of the...
