WebProperties of materials that can be exploited for the making of a thermometer include: volume of a liquid (Mercury thermometer), electrical resistance, color (frequency) of emitted light from a heated object, volume of a gas, expansion of metal (bimetallic strip). 3. Which is larger, 1 C or 1 F (degrees)? 1C is larger than 1F. WebTemperature. Most metals are good conductors of heat and they are solids at room temperature. Mercury is a good conductor of heat. It is used in thermometers because it has a high coefficient of expansion. Its stage indicates the temperature as rapidly as potential and perfectly. Mercury is the only one in a liquid state at room temperature.
WebIt was also commonly used in batteries, fluorescent lights, felt production, thermometers and barometers. Again, these uses have been phased out. Mercury easily forms alloys, … WebPhysical Properties. Mercury cannot be used below the temperature at which it becomes solid, -38.83 °C (-37.89 °F). If the thermometer contains nitrogen, the gas may flow down into the column when the mercury solidifies and be trapped there when the temperature rises, making the thermometer unusable until returned to the factory for reconditioning.
