1.Question 1What causes heat transfer?1 pointA difference in mass flowA difference in temperatureWork transferA difference in specific volume
Solution 1
The cause of heat transfer is a difference in temperature. When there is a temperature difference, heat will naturally flow from the area of higher temperature to the area of lower temperature. This is a fundamental principle of thermodynamics.
Solution 2
The cause of heat transfer is a difference in temperature. Heat naturally flows from a higher temperature area to a lower temperature area until equilibrium is reached. This is the second law of thermodynamics.
