Yes it can. Depending on the other conditions such as pressure, the water will be in differing states. For example, water will boil at 100 deg C and become a gas, the vapor can then be superheated to temperatures above 100 deg C at a standard pressure of 1 ATM.
Water kept in a sealed container under pressure can become superheated liquid, mainly due to the pressure within the container that keeps the liquid-vapor equilibrium such that the liquid is maintained at temps above 100 deg C.
Water can also superheat if there is a lack of nucleation sites such as bubbles from which boiling can occur. In this case the pressure not need be greater than 1 ATM to occur.
Over the superheated temperature range the extensive hydrogen bonds break down, changing the properties more than usually expected by increasing temperature alone. Water effectively becomes less polar and behaves more like an organic solvent such as methanol or ethanol. Solubility of organic materials and gases increases by several orders of magnitude and the water itself can act as a solvent, reagent and catalyst in industrial and analytical applications, including extraction, chemical reactions and cleaning. Viscosity and surface tension of water drop and diffusivity increases with increasing temperature. Self-ionization of water increases with temperature, and the pKw of water at 250 deg C is closer to 11 than the more familiar 14 at 25 deg C. This means that the concentration of hydronium ion (H3O+) is higher, and hence the pH is lower (although the level of hydroxide (OH-) is increased by the same amount so the water is still neutral). Specific heat capacity at constant pressure also increases with temperature, from 4.187 kJ/kg at 25 deg C to 8.138 kJ/kg at 350 deg C. The dielectric constant (relative permittivity) decreases significantly as the temperature rises, which has a significant effect on the behavior of water at high temperatures.

When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
Why is steam so dangerous?
Because in order to turn water into steam (liquid to gas) it must be heated intensely past the point of boiling, therefore the resulting steam is obviously extremely hot. If you are referring to the danger of a catastrophic pressure vessel failure (boiler explosion) the danger comes from a three-pronged issue. Water under pressure will not boil at 212 degrees (100 C). As the pressure goes up, so does the temperature need to get the water to boil. When a pressure vessel fails, there is the potential for an instantaneous drop in pressure from X pounds per square inches to ZERO psi. But of the water is (for example 350 degrees F) then without the pressure it will flash boil into steam. This is the thery of why locomotive boiler explosions were so deadly. It was common theory that when the firebox's roof sheet failed and the steam in the boiler evacuated into the firebox, the water flsah boiler, instantly raising the pressure to 50 to 100,000psi.
What is the boiling point of hexane?
Think in terms of room temperature. Hexane is a liquid that is flammable, but is used in cleaning solvents and stuff like around the garage. Propane is the gas that comes in a steel bottle that you use for gas stoves and barbeque grills. So if you let propane out into the room its a gas and so it already past its boiling point. So the boiling point of Hexane is hotter than room temperature and the boiling point of propane is lower than room temperature. The actual numbers are 69 C and -42 C.
What causes water to resist the temperature change?
Waters density is at the highest just a few degrees (4°C, or 7°F) above freezing, and it decreases as its temperature changes in either direction(this is pure water, salt water or other solutions may behave differently). This is due to the unique crystal structure water takes on as it freezes and becomes ice, the crystal lattice being less dense than a more conventional solid state substance.Read more: http://wiki.answers.com/Why_does_water_do_the_opposite_of_other_fluids_when_the_temperature_changes#ixzz1EpsbT1DD
When sodium melts what happens?
When sodium melts, it transitions from a solid state to a liquid state. The bonds holding the sodium atoms in a rigid lattice structure break, allowing the atoms to move freely and flow past each other. This process occurs at a specific melting point temperature for sodium, which is around 98 degrees Celsius.
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
Is it 100 degree Celsius or 100 degrees Celsius?
To calculate from Celsius to Fahrenheit, 1. Multiply by 9 100 * 9 = 900 2. Divide by 5 900 / 5 = 180 3. Add 32 180 + 32 = 212 So, 100ºC = 212F.
Does water get any hotter if you keep heating it past 100 degrees?
Water does not get hotter than 100 degrees because of a heating curve. During a phase change (in this case vaporization) the temperature remains the same. Once the phase change is complete the temperature will continue to rise but the water will have been completely evaporated. So no, water can not be heated to more than 100 degrees Celsius.
What is the past tense of boil?
The past tense of boil is boiled.
How hot does water need to be to boil?
On the Celsius scale and at Sea level, water boils at 100 degrees.While it is boiling the temperature of the water remaining in the container will stay at 100 degrees no matter how hot you make the fire.
What is the abbreviation of Celsius?
'C'It is also used to mean 'Centigrade'.Celcius is the correct term.There were other centigrade scales used in the past, that subdivide the scale into 100 units (centi-).Celcius scale has 0 at the freezing point of water and 100 at the boiling point of water.
What is the past tense of the word boil?
The past tense of boil is boiled.
How chlorine gas is liquified?
cool it down past it's boiling point (about -34 degrees celsius)
Why can't mercury thermometers go past -40?
Mercury thermometers can go past -40 degrees Celsius. However, mercury freezes at temperatures below -39 degrees Celsius, so the thermometer will not be able to register lower temperatures accurately.
What is the past of boil?
boiled
What is the past participle of boil?
The past participle is boiled.
What is the difference between Celsius and Centigrade?
What is the differences of Celsius and Fahrenheit thermometer? Don's say centigrade, say degrees Celsius. Look for the differences yourself. Here is a nice temperature converter. Scroll down to related links and look at "Conversion of temperatures and formulas".
