A thermometer is removed from a beaker of boiling water and placed in a beaker of room temperature water. The thermometer takes 15 seconds to reach a reading of 25°C. The same thermometer is returned to the boiling water for several minutes. It is then placed under a tap of running water at room temperature. The thermometer takes only 10 seconds to reach a reading of 25°C.
What conclusion could you make about conduction and convection based on these observations?
Your
Conduction is a more efficient method of heat transfer.
Convection is a more efficient method of heat transfer.
No valid conclusion is suggested by these observations.
Conduction and convection are equally efficient methods of heat transfer.
