Always here to help. Bring it!!!
The molecules which evaporate presumably take heat away from the liquid. So, I'd disagree with the classmate. Whether the amount of cooling would differ from the usual case wherein the molecules have different speeds is another question.
I guess the argument goes something along the lines of that the faster moving and therefore most kinetically energetic molecues evaporate and take away most heat. But if there's no faster moving molecules, 'cos they all have the same speed well, then presumably they'd all take away the same amount of heat. So, maybe the cooling would be less. No cooling though ??? Hmmmm dunno .... i think not ....
Answer:
Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,
when the distance between the two object is increased the gravitational force decreases by its square,
and when the mass an object increases the gravitational force also increases,
therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.
Hope it helped u,
pls mark as the brainliest and put thanks
