Which of the following statements is FALSE?

A A thermometer measures temperature.
B A barometer measures atmospheric pressure.
C A psychrometer measures wind pressure.
D An anemometer measures wind speed.
AI Explanation

The correct answer is C) A psychrometer measures wind pressure. A psychrometer is used to measure relative humidity, not wind pressure. It consists of two thermometers, one of which is a wet-bulb thermometer that measures the temperature of evaporating water. This allows the calculation of relative humidity, but it does not measure wind pressure. The other answer choices are correct statements: A) A thermometer measures temperature. B) A barometer measures atmospheric pressure. D) An anemometer measures wind speed.
