Explanation:
When water is heated up then its molecules move rapidly from one place to another. Hence, kinetic energy of the molecules tend to increase.
Also, K.E =
where, T = temperature
Therefore, more is the increase in temperature more will be the mean molecular speed change in the water molecules.
As a result, mean molecular speed change increases with increase in temperature and vice-versa.

Answer:
A
Explanation:
Since acceleration is the change of velocity and f=ma, the change in velocity is dependent on force and mass. Since the force on all of the objects is the same, the one with the least mass will accelerate the most. Object A is the least massive at a mass of 0.5kg, meaning that its velocity will change the most. Hope this helps!
