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 ....
Ocean currents are caused by density differences in the water and move water masses through the deep ocean
Answer:
Your brain is able to do this by comparing tiny differences in the way that sounds affect each ear. ... Signals from the ear travel along the auditory nerve to the brainstem, where each individual cell responds to a specific time difference and direction.
Explanation:
It's because of your ears.
I think it’s B. I apologize if I’m wrong.
Answer:
Friction is a big part of this. Rolling friction is acting on the bottom of the tires, and this causes the bicycle to keep rolling and not tip over. drag is the force that's pushing forwards opposite the bicycle, and gravity is the force keeping the bicycle on the ground.
