What is meant by ignition temperature?

Definition of ignition temperature : the lowest temperature at which a combustible substance when heated (as in a bath of molten metal) takes fire in air and continues to burn. — called also autogenous ignition temperature.

What is ignition temperature in one sentence?

The ignition temperature of a substance is the least temperature at which the substance starts combustion. Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.

What is ignition temperature for Class 10?

The lowest temperature at which a substance catches fire and undergoes combustion liberating heat and light is called ignition temperature. In other words it is the minimum temperature at which a combustible substance such as air or gas, must be heated up prior to burning in the absence of any source of the heat.

What is ignition temperature for Class 8 example?

Ignition temperature: It is the minimum temperature to which a combustible substance must be heated, before it catches fire. Therefore, we see that a combustible substance cannot catch fire as long as its temperature is lower than its ignition temperature e.g. Ignition temperature of phosphorus is 35 °C.

What is called ignition?

1 : the act of causing something to start burning. 2 : the process or means (as an electric spark) of causing the fuel in an engine to burn so that the engine begins working. 3 : a device that is used to start a motor vehicle Put the key in the ignition.

What is ignition temperature class 9?

Define the ignition temperature of a substance. Answer. The lowest temperature at which a combustible substance catches fire when heated in the air is called its ignition temperature of a substance.

What is ignition temperature by Brainly?

The autoignition temperature or fuel point of a substance is the lowest temperature where it immediately lights in a typical environment without an outer wellspring of start, like a fire or flash. This temperature is needed to supply the enactment energy required for burning.

What is ignition temperature class 7?

The lowest temperature at which a substance catches fire is called its ignition temperature.

What is ignition temperature Brainly?

Textbook solution The ignition temperature of a substance is minimal temperature at which the substance begins burning. Ignition temperature is the lowest temperature at which an ignitable substance when warmed (as in a bath of molten metal) takes fire in air and keeps on burning.

What is high ignition temperature?

Kerosene 295. Petrol 400. Alcohol 365. Hence the highest ignition temperature is of coal.

Which is the lowest ignition temperature?

Among the given options, kerosene has the lowest ignition temperature. So, it catches fire relatively easily. Which of the following substances has the lowest ignition temperature? Which of the two has a lower ignition temperature : petrol or kerosene?

What is ignition temperature and its example?

It is the lowest temperature at which substance catches fire. Substance cannot catch fire unless it reaches its ignition temperature. Example – Ignition temperature of Diesel is 210 degree celsius. It means it does not catch fire until it reaches 210 degree celsius. Note.

What does the term ignition temperature mean?

Definition – What does Ignition temperature mean? Ignition temperature is the minimum temperature at which a volatile material will vaporize into a gas and ignite without help from an external fire source. This lack of an additional ignition source makes a volatile material very dangerous especially when men and material are involved.

What is spontaneous ignition temperature?

The ignition temperature of a substance is the least temperature at which the substance starts combustion . Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.

What causes ignition modules to fail?

Because the ignition module is electronic and does not utilize moving components, it is normally one of the most reliable part of the engine. When it does fail, it is usually due to heat caused from improper wiring of the ground wire to battery voltage.

What is the ignition temperature of diesel fuel?

The ignition temperature of Diesel fuel No.1 ranges from 450 to 602 Kelvin, Diesel fuel No. 2 ranges from 527 to 558 Kelvin, and Diesel fuel No .4 is 536 Kelvin. No condition is permanent.
