Which of the following statements is true? which of the following statements is true?
a. in general, the solubility of a solid in water decreases with increasing temperature.
b. the solubility of an ionic solid in water decreases with increasing temperature.
c. the solubility of a gas in water usually increases with decreasing pressure. in general,
d. the solubility of a gas in water decreases with increasing temperature.
e. none of the above statements are true.

D

Explanation:

D is correct because an increase in temperature of the gas molecules causes an increase in the average kinetic energy of these gas molecules. It is practically like giving them more power to flow around. They thus try to leave the confines of the container and hence are less soluble

A is wrong. Most solids would become more soluble with temperature increase

B is wrong

C is wrong as a pressure increase would yield higher solubility

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
