Examples ofmetals are gold, silver, copper etc. Examples of non-metals are hydrogen, oxygen, iodine etc. Someelements have intermediate properties between those of metals and non-metals, they are calledmetalloids. A compound is a substance composed of two or more elements, chemically combined withone another in a fixed proportion. The material obtained by the group I is a mixture of the twosubstances. The properties of the mixture are the same as that of its constituents. Q.58) ________ is the only metal that is liquid at room temperature. a. silver b. gold c. copper d. mercury Q.59)The colourless gas with the smell of rotten egg is found in a. group II b. group IV c. group III d. group I Q.60)The constituent of compounds are separated by a. both chemical reaction and electrochemical reaction b. electrochemical reaction c. none of these d. chemical reaction

Diksha Laniya🐥 4 years, 4 months ago

Evaporation is a natural phenomenon where the molecules of a liquid convert into vapour and released free from the surface. It can happen at any temperature. ... It is because the water molecules absorb the heat of our body and convert into gas molecules. The heat lost from our skin makes us feel cooler.
