41. a 10.0-m3 tank contains steam at 275°c and 15.0 bar. the tank and its contents are cooled until the pressure drops to 1.8 bar. some of the steam condenses in the process. (a) how much heat was transferred from the tank? (b) what is the final temperature of the tank contents? (c) how much steam condensed (kg)?

this could be newton#'s law of cooling. the cooling curve is exponential

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.
