Point C
Calcium is a solid at its boiling point temperature, which is approximately 1,484 degrees Celsius. At this temperature, calcium would undergo a phase change from a solid to a liquid before reaching its boiling point to become a gas.
Alcohol thermometers are not suitable for measuring the temperature of boiling water because alcohol has a lower boiling point than water. The alcohol inside the thermometer would evaporate before reaching the temperature of boiling water, therefore providing an inaccurate reading.
It can not reach a boiling point because it decomposes before it boils.
Chlorine in water can affect the boiling process by increasing the boiling point of water. This means that water with chlorine will need to be heated to a higher temperature before it boils compared to water without chlorine.
It is generally recommended to start with eggs at room temperature before boiling them, as this can help prevent cracking during the cooking process.
The boiling point of water is 100 degrees Celsius. Glucose, on the other hand, does not have a fixed boiling point because it decomposes before reaching a boiling point.
Insulin does not have a boiling point, as it is a protein molecule that will denature (lose its structure and function) well before reaching a temperature close to boiling. Insulin is typically stored in a refrigerator to maintain its stability and effectiveness.
Iron filings do not have a specific boiling point because they are composed of tiny pieces of solid iron rather than a single compound. Iron itself has a boiling point of 2750°C (4982°F). Iron filings would typically oxidize and react before reaching this temperature.
By increasing the pressure on the water, you can raise its boiling point above 100°C. This can be achieved in a pressure cooker, where the increased pressure allows the water to reach a higher temperature before boiling.
Simmering.
The boiling point of sugar is approximately 366 degrees Fahrenheit (186 degrees Celsius). However, when sugar is heated, it will first melt and caramelize before reaching its boiling point.
Water - or other liquids - will evaporate at practically any temperature. Boiling is defined as the temperature at which the partial vapor pressure is equal to the atmospheric pressure. In practical terms, it means that the boiling water (or other liquid) can't get any hotter assuming the pressure doesn't change. You'll also see lots of bubbles rising from the boiling liquid (but before it is boiling, there will also be a few bubbles).
