Combustibility is not a physical property because?
combustibility is a chemical property. It describes how readily a substance will react with oxygen to undergo combustion. Physical properties, on the other hand, are characteristics that can be observed without changing the chemical composition of a substance, such as color or density.
When a substance is placed over a Bunsen burner it does what?
When a substance is placed over a Bunsen burner, it is heated. The heat causes the substance to undergo physical or chemical changes depending on its composition. This can lead to processes such as melting, evaporation, or combustion.
When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
How many hours will it take for a paper to undergo spontaneous combustion under 34.5 degrees celsius?
34.5 degrees Celsius = 94.1 degrees Fahrenheit, so, never! Paper ignites at about 451 degrees Fahrenheit and does not spontaneously go through combustion.
When equal amounts of energy are transferred to or from equal masses of different substance the substance will undergo different changes in temperature because of their different?
specific heat capacities. The substance with the lower specific heat capacity will experience a greater change in temperature compared to the substance with a higher specific heat capacity.
What is the energy barrier and how does it relate to the concept of ignition temperature?
The energy barrier is the minimum amount of energy required for a chemical reaction to occur. Ignition temperature is the minimum temperature at which a substance will ignite and sustain combustion. The energy barrier must be overcome for the substance to reach its ignition temperature and undergo combustion.
How does the substance react in the presence of air what happen if it is heated?
The substance may oxidize or undergo combustion in the presence of air, depending on its properties. If heated, the substance may decompose, vaporize, or react with air to release gases. It could also undergo thermal degradation or combustion, leading to potential hazards like fire or explosions.

Do substances actually burn in combustion?
Combustion is the process of rapid oxidation of a substance i.e. its rapid reaction with oxygen. This whole process is called burning. So, it can be said that the substance burns in combustion.
Can a substance undergo a chemical change?
A chimical property that indicates weather a substance can undergo chimical change

Why do only some substance burn with flame?
Substances that burn with a flame typically contain volatile components that vaporize easily when heated. These vapors can then mix with oxygen in the air and undergo combustion. If a substance does not have volatile components or if the conditions are not right for combustion (e.g., lack of oxygen), it may not produce a visible flame when burned.
Can sodium chloride undergo combustion?
No, actually sodium chloride can be considered the "ash" of burning metallic sodium in a chlorine gas atmosphere. The ash of combustion will not undergo further combustion.
Which gas undergoes spontaneous combustion?
There are many gases including chlorine and ammonia which can spontaneously undergo combustion.
