when price changes it is called inelastic demand and when quantity of demand change that is called elastic of demand.
Perfectly elastic demand. Relative elastic demand. Unit elasticity of demand. Relative inelastic demand. Perfectly inelastic demand.
it is perfectly inelastic
price elasticity of food would be inelastic, as there are no substitutes and food is a necessity.
marginal revenue is negative where demand is inelastic
Price elasticity of demand is used to determine how changes in price will effect total revenue. If demand is elastic(>1) a change in price will result in the opposite change in total revenue.(+P=-TR) When demand is unit elastic(=1) a change in price wont change total revenue. If demand is inelastic a change in price will result in a change in total revenue in the same direction.(+P=+TR)
Demand is unit elastic.

price elasticity of food would be inelastic, as there are no substitutes and food is a necessity.
there are five types.1).perfect elastic demand,2)perfect inelastic demand,3).relatively elastic demand,4).relatively inelastic demand4).unity elastic demand

I assume that when you say "elasticity," you mean "price elasticity of demand."Raise price a little. If total revenue goes up, you're in the INELASTIC region (where absolute value of elasticity is greater than 1). If it goes down, you're in the ELASTIC region.
if a price cut decreases total revenue, demand is elastic. if a price cut decreases total revenue, demand is inelastic. if a price cut leaves total revenue unchanged, demand is unit elastic.
A)
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.
Perfectly inelastic demand, perfectly elastic demand, elastic demand, inelastic demand etc.
