Do all substances catch fire on same temperature. Give reasons?
No, different substances have different ignition temperatures. This is because the ignition temperature is the specific temperature at which a substance will ignite and start burning. Factors such as chemical composition, molecular structure, and presence of impurities determine the ignition temperature of a substance.
The ability of a substance to support burning is called flammability?
Flammability is the ability of a substance to ignite and sustain combustion in the presence of an ignition source. It is influenced by factors such as the substance's ignition temperature, ease of ignition, and the presence of flammable vapors. Flammable substances can pose fire hazards and should be handled and stored with appropriate precautions.
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
The order in which the substances will exhibit the highest increase in temperature is C, B, A. This is because substance C has the lowest heat capacity, so it will increase in temperature the most with the same amount of heat added. Substance A, with the highest heat capacity, will increase the least.
Which substance has the highest specific heat?
Water has the highest specific heat capacity of any common substance. This means it can absorb a large amount of heat energy before its temperature changes significantly. This property of water helps regulate Earth's climate and moderates temperature changes in both aquatic and terrestrial environments.
What is the ignition temperature of natural gas?
The ignition temperature of natural gas typically ranges from 900 to 1500 degrees Fahrenheit (482 to 816 degrees Celsius).
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature is lower than the room temperature, the substance will not ignite or burn spontaneously at room temperature. Ignition temperature refers to the minimum temperature required for a substance to ignite and sustain combustion, so if it is lower than the room temperature, the substance will remain stable at that temperature.
What is the difference between ignition temperature and spontaneous ignition temperature in a fuel cell?
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
Is the ignition temperature of a substance is fixed?
Yes, as long as there is a spark or flame to ignite the substance.
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.
Which substance has the highest density at room temperature?
At room temperature, osmium is the substance with the highest density. Osmium has a density of around 22.59 grams per cubic centimeter, making it the densest naturally occurring element.
Which has a highest starting ignition between petrol n diesel?
Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine

What is an autoignition?
An autoignition is an act of spontaneous ignition, often triggered when a substance reaches a certain temperature.
Which room would have the highest average kinetic energy?
The room with the highest temperature would have the highest average kinetic energy, as temperature is a measure of the average kinetic energy of particles in a substance.
Which substance has the highest density at room temperature out of water hydrogen and oxygen?
mercury
What is the definition of auto-ignite?
Auto-ignite refers to the spontaneous ignition of a substance without an external ignition source, typically due to high temperature or pressure. It occurs when the substance reaches its auto-ignition temperature or pressure and ignites without the need for a spark or flame.
What are ignition points?
Well ignition points is the minimum temperature at which a substance will continue to burn without additional application of external heat. Also called kindling point.
