Fill in the blanks to make the statement correct. You must type the answer in exactly as it is in the word bank. If you type kinetic energy instead of KE it will be marked wrong. Before a ball is dropped, the ball has . When the ball falls, the ball then has GPE and KE. When the ball hits the surface, the ball transfers some of its to the surface before it bounces back up. If the surface the ball bounces on is , then most of the energy will not be absorbed because the molecules are close together.

Word Bank:

close together

friction

farther apart

KE

dense

not dense

GPE

GPE and KE

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
