At normal atmospheric pressure, water begins to freeze (turn into solid ice) at zero degrees centigrade.
ACTUALLY:
If saturation occurs at temperatures between 0 degrees Celsius and -4 degrees Celsius , the surplus water vapor invariably condenses into
SUPERCOOLED WATER(water having a temperature below the melting point of ice, but nonetheless existing in a liquid state).
Ice does not form within this range of temperatures.
Gas? Nearly there. Its actually called water vapour. In industrial situations it would be called steam.
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
The temperature in Celsius at which water boils is 100 degrees.
reaches its boiling point and starts to vaporize, turning into steam.
The enthalpy change for converting 1 mol of ice at -50 degrees Celsius to water at 70 degrees Celsius is the sum of the enthalpy changes for the following processes: heating ice from -50 degrees Celsius to 0 degrees Celsius (heat of fusion), melting ice at 0 degrees Celsius, and heating water from 0 degrees Celsius to 70 degrees Celsius (specific heat of water).
When water reaches 0 degrees Celsius, it freezes and transforms into ice. At this temperature, the kinetic energy of the water molecules decreases, causing them to slow down and form a solid crystalline structure.
At 100 degrees Celsius, water reaches its boiling point and starts to change from a liquid to a gas. This temperature remains constant until all of the liquid water has been converted into steam.
It is a solid
When the water at 20 degrees Celsius is placed in a freezer set at -10 degrees Celsius, the water will begin to lose heat to the surroundings. As a result, the temperature of the water will decrease until it reaches the equilibrium temperature of -10 degrees Celsius. At this point, the water will freeze and turn into ice.
water will become colder
Water reaches maximum density at 4 degrees Celsius
it will boil once it reaches 100 degrees Celsius
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.
4 degrees Celsius, at which point it reaches its highest density. Below 4 degrees Celsius, water expands as it freezes into ice.
At -20 degrees Celsius, water typically freezes and turns into solid ice. This is below the freezing point of water, which is 0 degrees Celsius.
The thermometer would show a gradual increase in temperature from -10 degrees Celsius as the water is heated. Once it reaches 0 degrees Celsius, the temperature will plateau until all the ice melts. Then, the thermometer will continue to rise above 0 degrees Celsius until it reaches over 110 degrees Celsius as the water boils.
Water reaches a roaring boil at 212 degrees Fahrenheit or 100 degrees Celsius.
