Under steady state, a compressor is used to increase the pressure of an ideal gas air from 100 kpa to 1 mpa. meanwhile the temperature is also raised from 300 k to 500 k. to be safe, a separate stream of water is used to cool the air down to 320 k while the pressure of air remains unchanged during the cooling process. the temperature of the cooling water increases from 15°c to 30°c, while the pressure of the cooling water remains the same at 1 bar approximately. assume the kinetic and potential energy change is negligible, there is no stray heat transfer from the heat exchanger to the surroundings. draw a p-v diagram, one for air identify state 1 to 3 on air p-v diagram. show work for how to obtain relative pressures and temperatures for this p-v diagram.

the higher the current the higher the mag field around it the higher the influence on the compass

not moving. pos accel,

a=d/t

a="triangle"v/t

explanation:

a = acceleration

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.
