A barometer is a scientific instrument used to measure atmospheric pressure. It helps in determining weather patterns as changes in atmospheric pressure can indicate approaching weather systems. There are two main types of barometers: Mercury barometers and aneroid barometers.

Why water is not suitable to be used in barrometer?
If water is used hight of water colomn would be very high.
What are two advantages of aneroid barrometer over mercury barrometer?
Two advantages of an aneroid barometer over a mercury barometer are that aneroid barometers are generally more portable and do not pose a risk of mercury exposure if broken, making them safer for handling. Additionally, aneroid barometers do not require the use of toxic mercury, which is better for the environment.
Which measuring device used in cooking or candle making options are barrometer wind vane thermometer or rain gage?
glass tube
If the barrometer rises does the temperature rise?
Not necessarily. A rise in barometric pressure typically signals fair weather and not a direct correlation with temperature. Temperature changes can be influenced by various factors beyond just barometric pressure.
