At room temperature, thermometers P and Q show the same reading. Thermometer Q’s bulb is covered with gauze and placed in a beaker of water at room temperature. Air at room temperature is then blown across the bulbs of both thermometers. Which statement gives the correct description and explanation of the result?
- AP reads higher than Q because bulb P absorbs energy from the air.
- BP reads higher than Q because water evaporates from the gauze and cools bulb Q.
- CP reads lower than Q because the wet gauze insulates bulb Q.
- DP reads lower than Q because water evaporates from the gauze and warms bulb Q.
