Heat Transfer - Engineering
Q1: For gases, the thermal conductivity increases with temperature rise. For liquids, with increase in concentration, its thermal conductivity generallyA decreases
B increases
C remains unchanged
D increases exponentially
ANS:A - decreases For liquids, the thermal conductivity generally increases with an increase in concentration. This is because higher concentrations often mean a higher density of molecules, leading to more frequent collisions and interactions between them. These interactions facilitate the transfer of thermal energy through the liquid, resulting in an increase in thermal conductivity. So, the correct answer is: "increases" |
