Above 4° Celsius water expands slightly as its temperature increases, this is due to the faster moving molecules taking up more space when they hit each other.
Water is most dense at 4° Celsius (density of 1,000) at 100°C the density is 0,958 kg/liter
Ice floats on water because it is less dense than the liquid phase.

What two factors influence density?
Temperature and Pressure! As temperature increases, density will tend to decrease. Conversely, as pressure increases, density will increase. I say "tend to" because water will actually expand as temperature reduces through its freezing point! Cheers, Robin
What is it when something absorbs heat?
What happens is that the molecules will move faster causing the object's temperature to increase and expand.
What expands and how does that expansion indicates the temperature?
Solid,Liquids,Gases expand when heated. Heat makes the particle attraction low hence the space between the particles increase and the thing expand. The expansion is the increase in the moleculer space of substances.
Why is hot water poured to a drinking glass more likely to break the glass?
The hot water will increase the temperature of the glass and cause the inside of the gas to expand faster than the outside.This will exert a force on the glass and the glass may crack.
What happen to solid when they absorbs heat?
Such a solid will either: a) Increase in temperature b) Melt c) or both
What causes a substance to expand?
An increase in temperature of the substance causes it to expand.
Do solids change volume?
Most solids expand as they increase in temperature and contract as they get colder. Interestingly, water after it freezes will start to expand as it gets even colder.
Does co2 expand when subjected extreme heat?
Volume is proportional to temperature, so if there is any increase in temperature, the volume of the gas will increase proportionally
Does the volume of water affect the temperature increase when reacted with calcium oxide?
yeah the temperature does increase, when you increase the volume of water the temperature of calcium hydroxide increases too!
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle caused by an increase in temperature.
You can increase the pressure of gas by doing what?
You could decrease the volume available to the gas or by increasing the kinetic energy of the particles. Although, after initial increase in temperature, the gas loses its ability to expand on increase in temperature.
Why does temperature of water lowers on adding glucose?
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.

How does hot water expand?
as we heat water,its temperature rises and the molecules start acquiring energy and collide with each other at an increasing rate..this makes water to expand..
What is it when something absorbs heat?
What happens is that the molecules will move faster causing the object's temperature to increase and expand.
Why does water evaporate from your cup?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; but a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase.
Does the volume of salty water increase when its temperature increases?
Yes, though it is slight, the volume increase is measurable when the temperature of salt water increases.
