believed that classical conditioning occurred because the conditioned stimulus became a substitute for the unconditioned stimulus when paired closely together in time.

conditioned stimulus

Explanation:

the conditioned stimulus paired closely together in time

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.
