I see this is not in the economics section and it is an economics question.
Inelastic: Price does not vary quickly with supply and demand
Possible reasons:
One of the above reasons works in reverse to the way you would think so use the examples carefully
Price inelastic
A good is inelastic if after a 1% increase in price the quantity demanded falls by less than 1%. Essentials such as petrol tend to be inelastic as do addictive products such as cigarettes.
Price inelastic means that the supply or demand of a product or service is unaffected by any changes in the price.
elastic
product whose demand is elastic are jewells(gold,silver,platinum,dimond,etc) fuel(petrol,disel,kerosene,etc) sugar detergents soaps(washing and bathing) products whose demand is inelastic are salt fruits food and vegetables

price elasticity=%change in quantity divided by %change in price it's inelastic when the absolute value of price elasticity is between 0 and 1
There are 2 different types price elasticity of demand and price elasticity of supply. If you meant to ask is demand for coal price elastic on inelastic, answer is yes, it is price inelastic. The demand for coal, is unlikely to drop much even if the price of it increases, it can be said that it is a 'necessity'. Since the quantity demanded decreases less than proportionate than the increase in price, it is said to be price inelastic.
price elasticity of food would be inelastic, as there are no substitutes and food is a necessity.
Inelastic It is inelastic because it is a necessity, which is a factor that determines price elasticity, bread is a staple diet around the world which makes it a need and therefore a necessity which is inelastic.
Increase. Inelastic demand means that most consumers will continue to buy a good regardless of price.
when price changes it is called inelastic demand and when quantity of demand change that is called elastic of demand.
An elastic item benefits from price decreases whereas an inelastic item does not.
