Ice melts at 0 degrees Celsius
Water boils at 100 degrees Celsius
Melt.
You can't melt water as melting is the transistion from solid to liquid and water is already liquid. And, if you are referring to ice, saltwater does not freeze terrestrially.
It does melt. If your honey crystalizes in the bottle, you can turn it back to liquid by putting the bottle in hot water.
Elemental sodium would melt very rapidly in liquid water of any temperature, and the hydrogen it produces self-ignites.
You could possibly arrange an experiment for different substances to melt and boil at the same time, but they would not do so at the same temperature. Different substances have different properties, they do not all melt and boil at the same temperature.
Melt.
No. Many substances melt and boil. Most of the elements, and many substances melt and boik without decomposition.
The kitchen range (cookstove) can heat ice (a solid) melt it to water (a liquid) and boil the water into steam (a gas)
Liquids can't melt. Melting is when a solid turns into a liquid. Since it is already in the liquid state, it can only evaporate, or boil.
If you are a solid, you melt. If you are a liquid, like water, you vaporize.
The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).
Ice is water, so if you heated it it would melt into liquid water before it could boil. The boiling point of water, of course, is 100 Celsius or 212 Fahrenheit (at sea level).
yes you can but it melts the butter
heat
vacuum is measured in inches of mercury. sea level is zero. water will boil at 212F. as negative pressure or elevation increases the boiling temp. of water decreases. if you had a pressure reading of 29.7 in" of mercury the water will boil at 192F. if you had a pressure reading of 10 in" of mercury water will boil at 32F
heat
The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.
