A200 kg chunck of lead falls from a hight of 30m and smashes into a rigid floor. calculate the increse in internal engery

Explanation:

Given:

mass of lead chunk,

height of the fall,

So, increase in the internal energy of the system after the collision is :

i would say the answer is food.

hope this !

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
