Answer 1

Right answer is (b) Barometer

The best explanation: Barometer is a device used to measure air pressure. Odometer is a device used to measure the distance travelled by a wheeled vehicle (it is the speed indicator in your vehicle). Dynamometer is a device used to measure torque or rpm of an engine. Hydrometer is used to measure specific gravity of liquids.                                                                                                                                                                            Also keep in mind that the liquid used in a barometer is mercury.
