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.

What liquid expands the most when heated?
Among common liquids, ether has a particularly high coefficient of thermal expansion.
What is expansion of liquid?
expansion of liquids
Why is water strange in thermal expansion?
Unlike most substances, when water freezes, it forms a structure that is less dense than the liquid it is in equilibrium with (which is why ice floats on liquid water). It is also unusual in that the maximum density of the liquid reaches a minimum at a temperature ABOVE the freezing point - roughly 1.0000 g/cm3 at 4 °C - before it begins to increase as it approaches the freezing point. Water thus has a negative coefficient of thermal expansion between 0 °C and 4 °C and a zero coefficient right at 4 °C. Other substances have uniformly positive coefficients of thermal expansion.
What is apparent and real expansion of liquids expansion?
Apparent expansion of a liquid is the increase in volume which appears to have taken place if no notice is taken. Real expansion is the actual increase in volume of a liquid per unit volume per degree rise in temperature
Does the cubical expansivity of a liquid depend on its original volume?
No. The expansivity is on a per unit basis just like the specific heat or density is.
Why is liquid safer than gas?
Coefficient of cubical expansion for liquid is much less than that of the gaseous form. So to avoid burst due to rise in temperature liquid is safer than gas.
Why cant you use alcohol in the thermometer?
You can ... but its a poor choice. (Range of temps that alcohol is a liquid, coefficient of expansion, volatility.)
What liquid expands the most when heated?
Among common liquids, ether has a particularly high coefficient of thermal expansion.
Were non-waxed taper wicks invented in colonial time?
A glass beaker is completely filled with 456 c.c. of a liquid when both the glass beaker and the liquid are at a temperature of 33.3oC. If the glass beaker and the liquid are cooled to 5oC. what additional volume of liquid (in c.c.) can be put into the beaker?Volumetric coefficient of expansion of liquid is 0.000109K-1 and the coefficient of linear expansion for glass is 3.2X10-6K-1
Why does the thermometer fill with mercury?
It's used in thermometers because it has high coefficient of expansion. also it's the only metal in a liquid state.
What is the thermal expansion coefficient of ammonia gas at standard temperature and pressure?
Most of the time when you encounter argon and nitrogen they will be gasses. Until you get up to high pressures, they will both behave more or less like ideal gasses. For an ideal gas, the volumetric thermal expansivity (i.e. relative change in volume due to temperature change) is: ßp = 1/T where p denotes a constant pressure process. The coefficient of linear expansion can be calculated from this to get: α ≈ ßp/3 For liquids, the value has to be measured because it certainly isn't an ideal gas when it is liquid! For liquid argon, the coefficient of thermal expansion is reported to be 0.01113 1/°C. For liquid nitrogen, the coefficient of thermal expansion is reported to be 0.00753 1/°C Note that you have to get down to cryogenic temperatures to liquefy argon and nitrogen and it tends to be under pressure when stored in a closed vessel.
How do you increase accuracy in a liquid in glass thermometer?
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.
What is the formula for calculating volume change due to heat?
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).
What is expansion of liquid?

What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
What is the scientific name for the inrease in the size of a substance when the temperature is increased?
Thermal Expansion. Each liquid or pure solid has a specific thermal of expansion. The thermal expansion of a substance is not linear, though for most of the temperatures we encounter in normal life, it is close enough to linear to be able to use a linear definition called the "Coefficient of Thermal Expansion".
