On a hot day, a student places a glass of cold lemonade on a table outdoors. After a few minutes, water droplets have formed on the outside of the glass. a) is energy absorbed or released by the cold lemonade? Explain your answer.
b) Compare average kinetic energy for the air molecules and lemonade molecules when the student first places
the lemonade outdoors. Explain your answer.
c) Explain how and why the water droplets form on the outside of the glass.

it is the most commonly accepted one

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
