Question
How is it “possible” to build a heat engine with an efficiency of 100%?operate the heat engine in an environment at 0 degrees Kelvin
operate the heat engine at an engine temperature of infinity
both of the above
neither of the above
If the temperature of object A is higher than the temperature of object B, what will happen if we place the two objects in contact (presuming that neither is losing or gaining energy through heat with any other object)?
the temperature of A will fall and the temperature of B will fall
the temperature of A will fall and the temperature of B will rise
the temperature of A will rise and the temperature of B will rise
the temperature of A will rise and the temperature of B will fall
the temperature of A will fall and the temperature of B will not change
the temperature of A will rise and the temperature of B will not change
Explanation / Answer
both of the above the temperature of A will fall and the temperature of B will fall
