I have a bucket of icewater with 100 grams of ice and 900 grams of liquid water all at zero degrees Celcius. I throw a hot chunk of iron into it (after which no heat enters or escapes the system), and the final temperature is 100 degrees Celcius with the ice having melted and some of the water actually boiling. The mass of the iron is 465 grams, and its initial temperature is 3,260 degrees Celcius. How many grams of water actually boil? (Don't write the unit, just the number.) You'll need these numbers: Specific heat of water: 4.2 J/g/deg Specific heat of iron: 0.46 J/g/deg Heat of fusion of water: 340 J/g Heat of Vaporization of water: 2300 J/g
Latent heat and phase change
A physical process in which a conversion among the basic states or phases of matter, i.e., solid, liquid, and gas takes place under the effect of a certain temperature and pressure is referred to as a phase change. Generally, the phase change of a substance occurs when heat transfer takes place between the substance and its surroundings. Based on the direction in which heat transfer takes place, different types of phase changes can occur.
Triple Point of Water
The branch of physics in which observer deals with temperature related properties is called thermodynamics.
Boiling Point of Water
Everyday examples of boiling is, boiling milk, heating water. One would have observed that when we heat water it goes through various stages and at one point bubbles show in water, and water keeps splashing with bubbles bursting, we in layman terms say that water is boiling.
Freezing Point of Water
In general, the freezing point of water is 0° Celsius, or 32° Fahrenheit. This is the temperature at which water will ordinarily change from its liquid state to its solid state (ice). However, there are certain conditions that can affect the freezing point of water. For example, a liquid may be supercooled or contain impurities so that it does not freeze at the ordinary freezing point.
