Predict whether a greater amount of energy will be transferred as heat between 1 kg of water at 10 degrees C and a freezer at -15 degrees Celsius or between 1 kg of water at 60 degrees C in an oven at 65 degrees Celsius

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

Which situation will produce the greatest change of momentum
