A student learns that the speed of the formation of a solution increases when the heat is supplied. How does heat affect the formation of the solution?
(a)change in temperature increases the size of the water particles (b)change in temperature changes the shape of the water particles (c)change in temperature changes the kinetic energy of the particles (d)change in temperature decreases the intermolecular spaces between the particles
Answers
Answer:
When heat is added to any substance, the particles gain energy and vibrates(with more speed) or vigorously about their fixed positions, forcing each other further apart. ... When heated there is increase in kinetic energy and particles move at higher speed.
a. An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume.
c. The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed. ... There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together.
d. On heating the solids, the intermolecular space between molecules: (A) Increases. (B) Decreases. ... Hence if we heat solids, it leads to the higher kinetic energy of particles and thus less intermolecular force of attraction.
