Is a boiling point a chemical property of a substance? Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties.
Is the ability to boil a substance a physical or chemical property? A substance’s boiling point is a physical property. For instance, when water (H2O) boils, so when it converts from a liquid to a gas or water to steam, it is still water. The chemical identity is still H2O. The chemical property hasn’t changed, only its physical property.
Why is boiling point not a chemical property? Boiling water: Boiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.
Is the boiling freezing point a physical property or a chemical property? physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.

How does boiling point depend on intermolecular forces?
Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point.
Can you boil vinegar in a kettle?
If you have distilled white vinegar on hand, add equal parts water and vinegar to the kettle until it is about halfway full. Bring to a boil; allow the boiled vinegar water mixture to sit in the kettle for 15 or 20 minutes.
What type of bacteria survive boiling water?
Clostridium bacteria can survive in boiling water even at 100 degrees Celsius, which is its boiling point for several minutes. This is because its spores can withstand temperatures of 100 degrees Celsius. However, all waterborne intestinal pathogens are killed above 60 degrees Celsius.

Why does water stop boiling when you stir it?
A water pot is small and non viscous, therefore the convection inside is strong enough to ensure that the heating is uniform. Therefore, stirring it won’t change the time to boil it, in itself. But stirring it will prevent to COVER the boiling pot.
