Jan 24, 2023 · bioluminescence, emission of light by an organism or by a laboratory biochemical system derived from an organism. It could be the ghostly glow of bacteria on decaying meat or fish, the shimmering radiance of protozoans in tropical seas, or the flickering signals of fireflies. The phenomenon occurs sporadically in a wide range of protists and animals, from bacteria and fungi to insects, marine ...

Jan 25, 2023 · Examples of physical changes are powdering of sugar, slicing, shredding, grating fruits and vegetables, and making ornaments out of gold. All of these are physical changes as the original substance remains the same but in a new form. All reversible changes and some irreversible changes are physical changes.

- Q.2. What are 3 examples of a physical change?Ans: The three examples of physical changes are: 1. Freezing of ice: When water is refrigerated or cooled, it solidifies to form ice. 2. Boiling of...
- Q.3. What are some of the characteristics of Physical Change?Ans: Some of the characteristics of Physical Changes are listed below: 1. No new substances are formed during physical change 2. Physical changes c...
- Q.4. Are physical changes reversible?Ans: Yes, physical changes are reversible. A change in which no new substances are formed can generally be reversed by reversing the conditions cal...
- Q.5. How is a chemical change different from a physical change?Ans: During a physical change, the appearance or shape of matter changes, but the type of matter in the material does not. In contrast, a chemical...
Jan 25, 2023 · thermal expansion, the general increase in the volume of a material as its temperature is increased. It is usually expressed as a fractional change in length or volume per unit temperature change; a linear expansion coefficient is usually employed in describing the expansion of a solid, while a volume expansion coefficient is more useful for a liquid or a gas. If a crystalline solid is ...
