Is this true that water contracts on cooling but it expands when cooled further from 4 degree C to 0 degree C?

Yes it contract and the expansion from 4 to 0 degrees is due to the crystallisation of water molecules.

How do you measure for an HVAC unit?
The answer depends on what you want to measure: the area to be heated or cooled, the power of the heating or cooling kit. Since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Examples of conduction in everyday life?
Some examples of conduction in every day life are when a hot object is cooled in a freezer, when a person takes a warm bath and hot food cooling down on a stove top....hope that helps :)))
Why would it be highly unlikely for temperature and dew point lines to criss-cross on a graph?
Dew point is supposed to be the temperature that water vapor is cooled to. If the air is colder than the condensation point (dew point) then it isn't being cooled.
Can flavored vodka freeze if less than half empty?
Yes. If cooled sufficiently.
What will happen as the temperature is gradually cooled at 10 degrees celsius?
It will gradually drop to below 10 degrees.
Does matter expand in heat or in the cold?
Matter typically expands when it is heated and contracts when it is cooled. This is due to the increased kinetic energy of the particles in the matter when heated, causing them to move further apart. Conversely, cooling matter decreases the kinetic energy, leading to the particles coming closer together.
Why does water expand on heating?
water expands on heating and contracts on cooling because when water is heated the molecules are closely packed and they overflow but when cooled they are loosely packed therefore they dont overflow. it is as simple as that.
When water at 4 degrees Celsius is cooled it does it contract?
Yes, water contracts when cooled from 4 degrees Celsius because it is in its densest state at that temperature. As it cools further, it expands until it reaches its freezing point, at which point it expands again and turns into ice.
Does water expand when cooled?
Yes, water expands when cooled below 4 degrees Celsius due to the formation of hydrogen bonds in its molecular structure. This expansion causes water to become less dense and eventually freeze into ice at 0 degrees Celsius.
Do any matter expand when cooled and contract when heated?
Yes, water is one example of matter that expands when cooled (turning into ice) and contracts when heated (turning into liquid water and then steam).
Which state of matter contracts more when cooled?
The solid state of matter usually contracts more when cooled compared to liquids and gases. This is because the molecules in a solid are already closely packed together, and cooling them further causes them to vibrate less, leading to a decrease in volume and contraction.
Is the expansion of a substance due to heat?
YES, as far as I'm concerned, a substance expands when heated and contracts when cooled.
Why mercury is used in making thermometers?
It was used because it is a liquid that expands and contracts to a usable degree when heated or cooled.
Matter expands or contracts to fill the space available?
Matter generally expands when heated and contracts when cooled. This is due to the changes in the kinetic energy of the particles within the matter. The expansion or contraction allows matter to adjust its volume to the space available.
What are the advantages and disadvantages when using rubber?
Advantages of Rubber is it is flexible and can be moulded into any shape. Disadvantages are when heated it expands and when cooled it contracts.
Which 3 solids contract on cooling?
Water contracts on cooling from 0°C to 4°C due to the formation of water molecules arranged in a hexagonal lattice structure. Ice contracts further upon cooling below 0°C as the molecules align into a more ordered arrangement. Most metals contract as they cool due to the decrease in thermal vibrations of the atoms in the crystal lattice.
Does water contract or expand when it is cooled?
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%
