What are the definitive characteristics of ser demand

Demand is called the economic factor by which market agents require a certain number of goods and / or services for consumption. Thus, the quantity of goods that these require is the quantity demanded.

Demand is directly influenced by two factors: the price of the good (the higher the price, the lower the demand, as the cost will be higher in relation to wages) and the quantity supplied (the higher the supply, the cheaper the good will be, as there will be availability for all consumers; on the contrary, the lower the supply, the more expensive the good will be as it will be subject to the laws of the market of supply and demand).
