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

∙ 12y ago— We can specify a liquid by its volume. Hence, we can speak of volume expansion only for liquids. Expansion of liquids is much greater than that of solids.
—
—A liquid is heated in a container. Heat flows through the container to the liquid. Which means that the container expands first, due to which the level of the liquid falls. When the liquid gets heated, it expands more and beyond its original level. We cannot observe the intermediate state. We can only observe the initial and the final levels. This observed expansion of the liquid is known as the apparent expansion of the liquid.

—If we consider the expansion of the container also and measure the total expansion in volume of the liquid, then the expansion is termed as the absolute expansion of the liquid.

Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
What is expansion of liquid?
expansion of liquids
Practical uses of thermal expansion of liquids?
randomness
Solid metals undergo greater thermal expansion than liquids do?
false
Liquids usually have higher volume coefficients of expansion than solids do?
that is TRUE
Why liquids have two coefficient of expansion?

Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
What is expansion of liquid?
expansion of liquids

What is meaning of real and apparent?
Real means existing in fact Apparent means obvious
Why are there laws only for gases and not for solids or liquids?
There are laws for solids and liquids, too. For instance solids have a coeffient of linear expansion and liquids (and gasses) have a viscosity. Many others.
Solid metals undergo greater thermal expansion than liquids do?
false
What is the definition of real expansion?
a real increase in the volume of a liquid that takes place due to increase of temperature is called real expansion
Liquids usually have higher volume coefficients of expansion than solids do?
that is TRUE
What is a sentence for thermal expansion?
Thermal expansion is the dimensional changes exhibits by solids, liquids, and gases for changes in temperature while pressure is held constant.
Formula to calculate real depth from apparent depth?
Real depth Dr= Apparent depth/ refractive index of water Dr= Da / n water
A thermometer works on the principle that a rise in temperature causes?
A rise in temp causes the expansion of the mercury or alcohol present in the tube.The graduation is done in such a way that the amount of expansion gives the temp.
