A→B: If the temperature increases, the particle speed is increasing; if the temperature is constant, the particle speed is staying the same; if the temperature decreases, the particle speed is decreasing.

Question

B→C: Similar to the above, if the temperature increases, the particle speed is increasing; if the temperature is constant, the particle speed is staying the same; if the temperature decreases, the particle speed is decreasing.

D→C: If this transition involves a loss of temperature, particle speed is likely decreasing; if the temperature is constant, the particle speed is staying the same; if the temperature is increasing, the particle speed is increasing.

E→D: Following the same logic, if this transition sees a drop in temperature, particle speed is decreasing; if it is constant, the particle speed is staying the same; and if it is increasing, the speed is increasing.

shorten all them

Answer 1

A→B: Increased temperature increases particle speed; constant temperature keeps speed the same; decreased temperature decreases speed.

B→C: Increased temperature increases particle speed; constant temperature keeps speed the same; decreased temperature decreases speed.

D→C: Loss of temperature decreases particle speed; constant temperature keeps speed the same; increased temperature increases speed.

E→D: Loss of temperature decreases particle speed; constant temperature keeps speed the same; increased temperature increases speed.
