Water has a high melting point and boiling point because of hydrogen bonds
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
Water it can melt in the boiling point and in the boiling point the water (ice) practically turns into a liquid (water) then into a gas
The boiling point is typically higher than the melting point for a substance. The boiling point is the temperature at which a substance transitions from a liquid to a gas, while the melting point is the temperature at which a substance transitions from a solid to a liquid.
Salt water has a lower freezing point and a higher boiling point.
Yes. Water melts at 0 ºC. Tetrachloromethane (Carbon tetrachloride) has a melting point of -22 ºC
You would need to look at a temperature / pressure graph
NaCl has the highest melting point (between NaCl and H2O)
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.
The melting point of water is zero degrees Celsius.
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
