compatible expansion/contraction characteristics -- linear expansion and contraction for the normal temperature range; low freezing point of -38 degrees C
iodine and Mercury
The two most commonly found liquids in liquid-in-glass thermometers are mercury and alcohol. Mercury thermometers are used for high-temperature applications, while alcohol thermometers are used for lower temperatures due to their lower toxicity.
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
Mercury and alcohol (typically ethanol or dyed alcohol) are two liquids that have been commonly used in thermometers. Mercury is often used in industrial thermometers due to its high thermal conductivity, while alcohol is used in household thermometers for safety reasons.
The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.
The main reason is that Mercury has almost no atmosphere which would hold the heat in. So the temperature on the side which is facing away from the Sun can plummet.
iodine and Mercury
it is used in thermometers(sorry if i spelled thermometers wrong)
The two vocals are used, drums are used, and the piano is used.
The first is to describe why something HAD TO happen. The second is to describe why something DID happen. Just "the reason" is what it is, and it can be used in three different ways. You used two of them in your question
Because the chemistry gods were smiling on us the day they came up with the flammable metals. Mercury vapor is dangerous enough as it is; can you imagine how bad mercury smoke would be?Okay, here's the real reason - and it's also the reason mercury is liquid at room temperature. Combustion is an exothermic oxidation process. Mercury's outer shell makes it very much like a noble gas. This trait does two things for us. First, it makes it noncombustible. The other is it makes it impossible for mercury atoms to bond into a solid mass.
Most commonly, the two substances used in a thermometer's glass tube are mercury and alcohol. Mercury is traditionally used in older thermometers, while alcohol (typically colored red) is used in modern thermometers as a safer alternative.
