examples: mass, density, color, boiling point, temperature, and volume. non examples- anything that's NOT a physical property will be a non-example. emotion is not a physical property. ... property or behavior of a substance when it undergoes a chemical change or reaction.
Physical properties can be observed or measured without changing the composition of matter. ... Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property.

In a food web, organisms are placed into different trophic levels. Trophic levels include different categories of organisms such as producers, consumers, and decomposers.
<span>Best Answer: Mn(ii) is catalyst
Stetep-1 is slow step
Steps-2,3 are fast steps
intermediates are Mn(iii)and Mn(iv)
since step -1 is slow rate depends on Ce(iv) and Mn(ii) only
not on Tl(i) as it is involved in fast step-3</span>
