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.
What is the Maximum service temperature of polypropylene?
The maximum service temperature of polypropylene is typically around 100 to 120 degrees Celsius (212 to 248 degrees Fahrenheit). However, this can vary based on the specific grade and formulation of the polypropylene, as some modified versions may withstand higher temperatures. It’s important to consider factors such as duration of exposure and the specific application when determining suitability for high-temperature use.
Is polypropylene a solid?
Any substance with a sufficiently large average molecular weight to be called "polypropylene" under normal circumstances is a solid at standard temperature and pressure. However, note that some hydrocarbons, such as hexenes, that could be formed by condensing small numbers of polypropylene molecules, are not solids at standard temperature and pressure.
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.
Why is the glass transition temperature of polystyrene greater than of polypropylene?
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
Which one has got higher ignition temperature wood or kerosene?
kerosene has got higher ignition temperature.
Ignition temperature is the minimum temperature required to?
burn
What is the melting point of polypropylene?
The softening temperature of polypropylene is 150 degrees Celsius. Its melting point is between 160 and 170 degrees Celsius.
What is temperature for ignition?
The temperature for ignition refers to the minimum temperature at which a material will catch fire and sustain combustion. This temperature varies depending on the material and its chemical composition.
What is the ignition temperature of natural gas?
1100-1200 degrees Fahrenheit is the minimum ignition temperature.
How does Polypropylene Keep you Insulated?
Polypropylene has a low thermal conductivity, which means it is a poor conductor of heat. This property helps trap air close to the body, creating a layer of insulation that helps retain body heat and keeps you warm. Additionally, polypropylene has moisture-wicking properties that help regulate body temperature by keeping sweat away from the skin.
What is the ignition temperature of yellow phosphorus?
The ignition temperature of yellow phosphorus is approximately 30-60 degrees Celsius. At this temperature, yellow phosphorus can spontaneously ignite in air.
