Student A described liquids.

6 0

Answer: Option (A) is the correct answer.

Explanation:

In solids, particles are attracted towards each other by strong intermolecular forces and they do not have enough gap between them. Therefore, they are orderly arranged.

In liquids, though the particles are close and touch each other but there are gaps between their arrangement. Therefore, they are randomly arranged as the forces of attraction are not strong enough like in solids.

In gases, particles are weakly attracted towards each other and they constantly moves from one place to another.

In plasma, there are charged particles which have similar number of positively charged ions and negatively charged electrons.

Thus, we can conclude that out of the given options, student A described liquids.

. What is the relationship between quantity demanded and quantity supplied at equilibrium? What is the relationship when there i
Zanzabum

Answer:

  • At equilibrium, the quantity of a commodity demanded is the same as the quantity of that commodity supplied. i.e. QD = QS. The price at which QD = QS is the equilibrium price.
  • When there is a shortage, the quantity of goods demanded would be greater than quantity supplied, as the price falls below the equilibrium price. i.e. QD>QS
  • When there is surplus, the quantity of goods demanded is less than the quantity supplied, as price increases above the equilibrium price. i.e. QD<QS.

For example, in the table showing the demand and supply schedule for T shirt at different prices (see file attached), the equilibrium price for a unit of T shirt is $3, at equilibrium, QD = QS (i.e. 30 = 30).

A shortage is recorded when the price of T shirt falls below equilibrium price of $3 as shortage of T shirt is recorded, i.e. @ $2, QD>QS (40>20). A shortage of 20 is recorded.

Surplus occurs as price increases above equilibrium price of which QD<QD, i.e. @ $4, a surplus of 20 is recorded.
