When water is boiled steam is produced?

Answer 1

Water at sea level boils at 212 degrees F or 100 degrees C, but as you boil your water higher and higher above sea level, the temperature needed to boil water lowers.

Interesting point: Climbers ascending the highest mountains find that in the high altitude, water will not boil hot enough to cook food.

Answer 2

Water boiling is a physical change from H2O in the liquid state to H2O in the gas state. The water molecule itself does not undergo a chemical change. It retains its chemical identity while undergoing a physical change.

Answer 3

H2O

Chemical composition can only be altered in chemical changes.

When water is boiled, it is a change of state, which is a physical change.

The main difference and way to separate the the types of changes is that chemical changes alter the Chemical composition (e.g. Burning, or making new substances) and cannot be reversed.

Whereas Physical changes are a change in state, or other reversible changes that have no effect on the actual Chemical comp.

Answer 4

When water is heated to its boiling point, it changes state from liquid to gas, resulting in the formation of steam. This occurs as the water molecules gain enough energy to overcome the forces holding them together in the liquid state, allowing them to escape into the air as steam.

Answer 5

Water boils when the air pressure equals the vapor pressure, which at sea level happens at about 212 degrees Fahrenheit.

Answer 6

Water.
