You may have noticed that in spite of carefully measuring and calculating, the values for the specific heat you determined experimentally do not match the published values for those concentrations of propylene glycol solutions. Let's explore why. 1. Rosa suggests a source of error: Some of the energy from the heating coil is lost because the insulation of the container is not perfect. What type of error will this cause

be subject to a force andchange its motion

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.
