When will water boil at a temperature less than 100 degrees Celsius?
Water can boil below 100 degrees Celsius depending on the area of the world. A lab was conducted in science class that our water boiled at 94.6 degrees Celsius. The average boiling point for water is 100 degrees Celsius but that does not mean it will always be that degree to boil.
If iodine melts at 114 degrees Celsius and boils at 184 degress Celsius what is its physical state at 250 degrees Celsius?
The answer is in the question Everything can be a solid, liquid or a gas. Below 114'C Iodine is solid, at 114'C it melts and becomes a liquid. Then at 184'C Iodine boils and becomes a gas, therefore above 184'C it is a gas. This is assuming that the pressure stays constant. Usually if you raise the pressure the boiling and melting point drop. For example at sea level water will boil at 100'C, on the summit of mount Everest (where the pressure is low) water will boil at 70'C. You can almost imagine the low pressure sucking the water into a gas, and the high pressure squashing it back into a liquid
Why do scientists prefer to use this scale over the Celsius or the Fahrenheit scale?
Because it is measured in even numbers with a 0 degree freezing point and a 100 degree boil.
When you boil something what happens?
A chemical change occurs when you boil something. Also, evaporation can occur when it gets hot enough.
How many syllables does boil have?
Two.
