Question
Ice on a car windscreen will disappear as youdrive, even without the heater on. Explain why thishappens
Solution
-
As you drive, the car's engine generates heat. This heat is transferred to the rest of the car, including the windscreen.
-
The heat transferred to the windscreen raises its temperature, causing the ice on the windscreen to melt.
-
The wind generated by the car's movement also contributes to the melting of the ice. This wind increases the rate of heat transfer from the warmer air to the colder ice, causing it to melt faster.
-
The melted ice, now in the form of water, is blown off the windscreen by the wind generated by the car's movement.
-
As a result, the ice on the car windscreen will disappear as you drive, even without the heater on.

The ice on the front windshield of the car had formed when moisture condensed during the night. The ice melted quickly after the car was warmed up the next morning because the defrosting vent, which blows on the front windshield, was turned on full force.Which of the following, if true, most seriously jeopardizes the validity of the explanation for the speed with which the ice melted?A) The side windows had no ice condensation on themB) Even though no attempt was made to defrost the back window, the ice there melted at the same rate as did the ice on the front windshield.C) The speed at which ice on a window melts increases as the temperature of the air blown on the window increasesD) The warm air from the defrosting vent for the front windshield cools rapidly as it dissipates throughout the rest of the carE) The defrosting vent operates efficiently even when the heater, which blows warm air toward the feet or faces of the driver and passengers, is on
