Knowledge About The World

A thermometer is an instrument used to measure temperature. It consists of a narrow glass tube with a bulb at one end that contains a liquid, usually mercury or alcohol. As the temperature changes, the liquid expands or contracts, causing it to rise or fall in the tube. The temperature is then read from a scale marked on the tube. A barometer measures atmospheric pressure, while a weight machine is used to measure the weight of an object. Therefore, the correct instrument to measure temperature is a thermometer.

A barometer is an instrument used to measure air pressure. It consists of a column of liquid (usually mercury) in a tube that is open at the bottom and closed at the top. As the air pressure increases, it pushes the liquid up the tube, and as the air pressure decreases, the liquid level drops. By measuring the height of the liquid column, the air pressure can be determined. This makes the barometer a suitable instrument for measuring atmospheric pressure and predicting weather patterns.

Maldives is the correct answer because it is the smallest Muslim country in the world. It is an island nation located in the Indian Ocean and consists of a chain of 26 coral atolls. With a total land area of only about 298 square kilometers, Maldives is the smallest country in Asia in terms of both land area and population. It is also known for its beautiful beaches, clear blue waters, and luxury resorts, making it a popular tourist destination.
