There is no exact answer. The coefficient changes with pressure, temperature and salinity. For seawater this value can be found in a paper by safarov, called thermal properties of seawater, table 11.

Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.
The apparent expansion of a liquid refers to the increase in volume of a liquid when its temperature rises. This expansion occurs due to the increased kinetic energy of the liquid particles, causing them to move farther apart. The amount of expansion is generally calculated using the coefficient of volume expansion.
No. The expansivity is on a per unit basis just like the specific heat or density is.
Oh, dude, you're hitting me with some science jargon there! So, like, the coefficient of volume expansion for freezing force is basically a fancy way of saying how much a substance's volume changes when it freezes. It's like when you put a can of soda in the freezer and it explodes because the liquid expands as it turns to ice. Just remember, freezing force is no joke, man!
The liquid in a glass thermometer is typically a non-toxic and non-reactive liquid such as mercury or colored alcohol. These liquids have a high coefficient of thermal expansion, allowing them to accurately measure temperature changes by expanding or contracting within the narrow capillary tube of the thermometer.

The coefficient of thermal expansion for liquid caustic soda at 50% concentration is approximately 0.0008 per degree Celsius (1/°C). This value indicates how much the volume of the liquid will change with temperature variations.
You can ... but its a poor choice. (Range of temps that alcohol is a liquid, coefficient of expansion, volatility.)
Liquid is generally safer than gas because liquids are easier to contain and control than gases. Liquids are denser and have lower vapor pressure, which reduces the risk of leaks and potential hazards. In addition, liquids are less likely to disperse rapidly and cause fires or explosions compared to gases.
Mercury is used in thermometers because it has a high coefficient of expansion, meaning it expands and contracts with temperature changes, making it easy to read. It also has a wide temperature range in which it remains liquid, allowing for accurate measurement in various conditions.
No. The expansivity is on a per unit basis just like the specific heat or density is.
There are several ways:use a liquid whose coefficient of thermal expansion is near constant,use a liquid with low vapour pressure,use a bulb with a relatively larger bulb and thinner stem,calibrate the thermometer carefully.

That depends on the exact details. For a gas, the ideal gas law is usually a good approximation: other things being equal, the volume is directly proportional to the absolute temperature (that is, the temperature expressed in kelvin). For a liquid or gas, the expansion is much less than in a gas. You can look up the coefficient of expansion for a specific substance, and then use the definition of the coefficient; that is, the volume change is equal to (volume) times (temperature difference) x (coefficient of volume expansion).
The liquid metal in many thermometer is mercury (Hg).
