Is water denser when frozen than when liquid?
The maximum density of water occurs at 3.98 °C (39.16 °F)Solid water, i.e. ice, has a density of 917 kg/m3 , so it is LESS dense than liquid.The liquid water density is 1,000 kg/m3 (at 4 °C)
When liquid water is heated to 100 C it boils and becomes water vapor When the vapor is cooled below 100 C it turns back into a liquid What is the correct name for the process in which the vapor?
(turns into a liquid) condensation
What phase is water in at 75 C and 9atm?
Liquid phase
What form does water take at 100 degrees c?
Liquid and Gas.
When liquid water is heated to 100 c it boils and becomes water vapor when the vapor is cooled below 100 c it turns into a liquid what is the correct name for the process in which the vapor turns?
When a gas (vapor) changes to the liquid phase, it is called condensation.
Why do lakes and ponds freeze from the top down rather than from the bottom?
One of the unusual properties of water is that it is actually less dense when it turns from a liquid to a solid - hence the reason ice floats on water. In its liquid phase water is actually at its maximum density at around 4 degrees C and then undergoes a slight decrease in density towards 0 degrees (then a large decrease upon freezing). This means that water at 4 degrees C is more dense and will tend to sink below water at a lower temperature. As such water less than 4 degrees C will float on top of the slightly warmer water and will be nearer the surface of the pond and so will freeze first.
When cold water sinks where does it go?
Water is most dense at 4° C and so because water at cold temperatures has a greater mass per volume it will sink below warmer water.
Does the volume change when a liquid is frozen?
It increases. Think of water: ice cubes take up more space than does the same amount of water when in liquid form.
At what Celsius water show high density?
Water is at its highest density at about 4 C. Below 4 C the molecules start to form a structure which increases the volume very slightly. At 0 C that structure becomes solid ice, which has about 17% less density that liquid water.

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 are the 5 characterics of Water?
odorless tasteless liquid expands upon freezing freezing point 0° C boiling point 100° C maximum density at 4° C
What does liquid water turn into?
Ice melts into liquid water at 0 degrees C, 32 degrees F.
What is the mass 150 cm to the third power of liquid water?
It will range from approx 149.996 grams at 4 deg C to 143.76 grams at 100 deg C.
Why can't liquid air have liquid water in it?
Liquid air is air (nitrogen, oxygen and other gases) that has been super cooled to change its phase from gas to liquid. At these temperatures, water will be solid. Water turns to ice at 0 degrees C. Nitrogen and oxygen turn to liquid (liquid air) at about -196 degrees C and -183 degrees C, respectively. Water went solid a long time ago when considering how cold these gases are as a liquid.
Is water a liquid at 30 degrees c?
Yes, water at 300c is quite warm and liquid.
When liquid water is heated to 100 C it boils and becomes water vapor When the vapor is cooled below 100 C it turns back into a liquid What is the correct name for the process in which the vapor?
(turns into a liquid) condensation
