In a science lab Cash mixes two clear liquids together in a beaker. Bubbles are produced and a white solid forms and settles at the bottom. He plans to heat the beaker over a low heat and make more observations. which statement is most likely correct?

A.) A physical change occurred so if cash heats up the white solid will disolve to form the origanal mixture of clear liquids.

B.) A physical change occurred so even if cash heats up the white solid will remain.

C.) A chemical change occurred so if cash heats up the white solid will disolve to form the origanal mixture of clear liquids

D.) A chemical change occurred so even if cash heats it the white solid will remain

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
