27 grams of 25.0 c aluminum is heated until its temperatures is 54 c. if the specific heat of aluminum is 0.90 j/g c , calculate the amount of heat energy needed to cause this rise in the temperature

q=mxcpx delta t

v. 656 j
w.705 j
x.608 j
y.0

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.
