Solubility is the property of a solid, liquid, or gaseous
chemical substance called solute to dissolve in a solid, liquid, or
gaseous solvent to form a homogeneous solution of the solute in the
solvent.

Why are clothes made out of a mixture of synthetic fibers and natural fibers more popular than those made purely out of synthetic fibers
🔄 Click to see definition
Definition1/14
Natural fibres are good to wear and comfortable. But their cost
is high. Synthetic Fibres are cheap but sometimes uncomfortable.
Manufacturers mix synthetic fibres with natural fibres so that
cloth they make get the characteristics of both synthetic and
natural fibres. They become comfortable to wear and cheap in
price..................................................

How can saturated and unsaturated hydrocarbons be differentiated on the basis of combustion
🔄 Click to see definition
Definition1/14
Saturated hydrocarbons sometimes burn with smoky flame upon
combustion while unsaturated hydrocarbons always burn with
non-smoky or blue flame. This is on account of the reason that for
the same number of carbon atoms in their molecular formula,
saturated hydrocarbons have more number of hydrogen atoms as
compared to unsaturated hydrocarbons.
