During the refrigeration cycle, what does the refrigerant do? absorbs and releases thermal energy by first vaporizing then condensing. absorbs and releases thermal energy by first condensing then vaporizing. insulates the thermal energy away from the cooling area. transfers thermal energy to the cooling area by condensing.

Answer :  Absorbs and releases thermal energy by first vaporizing then condensing.

Explanation :

The transfer of heat from one place to another is a function of refrigerant.

Initially, the liquid refrigerant enters the indoor coil. Here, it changes from liquid state to vapor state. Then this vapor refrigerant enters into the compressor.

Finally, it flows into the condenser. Here, It releases heat to the outside air.

So, refrigerant absorbs and releases thermal energy by first vaporizing then condensing.

its c i just checked it

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.
