Answer :
Final answer:
An air conditioner lowers the temperature and reduces humidity in a room by transferring heat and using an expansion valve. It also affects our perception of temperature by reducing humidity.
Explanation:
An air conditioner lowers the temperature and reduces the humidity in a room. It does this by using an electrically driven compressor to raise the temperature and pressure of the gas, and then forcing it into the condenser coils. The heat from the gas transfers energy to the room, causing the gas to condense into a liquid. The liquid then flows back through an expansion valve and returns to the outdoor evaporator coils to repeat the cycle .Humidity affects our perception of temperature because on humid days, sweat does not evaporate as efficiently. Relative humidity tells us how much water vapor is in the air compared to the maximum possible. The air conditioner helps to lower the humidity in the room, which can make it feel more comfortable. Overall, an air conditioner works to cool the air temperature and decrease the humidity in a room, providing a more comfortable indoor environment.
