ts surroundingsA B lt increases as the water absorbs energy from surroundings.its C It increases as the water releases energy to its surroundings. D. It decreases as water releases energy to its surroundings.
D. It decreases as water releases energy to its surroundings.
Explanation:
Kinetic energy is the energy associated with the speed of a body. If there is speed, surely there will be that kind of energy. For objects that are at rest, the kinetic energy is zero because the velocity of such bodies is zero.
Water molecules in liquid form are in constant motion, the greater the motion of these molecules the greater the kinetic energy in this system. However, as water moves from the liquid to the solid state, the velocity of the molecules begins to slow down and the energy begins to be released by the edges. From this we can conclude that in the solid state the kinetic energy of water decreases as water releases energy into the surroundings.
The correct answer among the choices listed above is option D. The average kinetic energy of water molecules as water freeze <span>decreases as water releases energy to its surroundings. Energy is released as the molecules go into a more condensed phase which is the solid.</span>
Leguminous plants like pulses etc. have root nodules comprising of rhizobacterium which live in a symbiotic relationship with the roots of the plant and in turn fix the nitrogen in the soil in the roots of the leguminous plants.
