High temperatures are needed to crack alkanes because it provides the necessary activation energy for the breaking of strong carbon-carbon bonds. These bonds are quite stable, so elevated temperatures are required to overcome their energy barrier and initiate the cracking process.

The reason a car's dashboard might crack when exposed to high temperatures?
High temperatures can cause a car dashboard to crack due to the expansion and contraction of the materials used in the dashboard. Over time, this repeated stress can weaken the dashboard, eventually leading to cracks. Additionally, prolonged exposure to UV rays can degrade the dashboard material, making it more prone to cracking.
What are two conditions needed to crack paraffin?
Two conditions needed to crack paraffin are high temperature (around 500-900 degrees Celsius) and the presence of a suitable catalyst. Cracking breaks down larger hydrocarbon molecules like paraffin into smaller, more valuable hydrocarbons like ethylene and propylene.
Which two things are needed to crack hydrocarbons?
Cracking hydrocarbons requires high temperatures (typically 500-900°C) and a catalyst to break down larger hydrocarbon molecules into smaller ones. This process helps produce valuable products such as gasoline, diesel, and ethylene for further refining or manufacturing.
What are 3 uses of alkanes?
Alkanes are used as fuels, such as gasoline and diesel, due to their high energy content. They are used as raw materials in the production of various chemicals and plastics. Alkanes are used as solvents in industrial processes and cleaning products.
What happens to crack cocaine if you wash it in the washing machine?
Washing crack cocaine in a washing machine will likely destroy the drug as it is water-soluble and sensitive to moisture. The high temperatures and agitation in the washing machine can break down the chemical structure of the drug, rendering it ineffective.
What is the reason a car's dashboard might crack when exposed to high temperatures?
thermal expansion
Why is it important to protect a spacecraft from extreme temperatures?
Temperatures can be very high endangering the spacecraft and the astronauts. Therefore, temperatures needed to be constantly monitored.
Why do Earthenware dishes crack?
Because they are fire-baked at very high temperatures to make them usable at high temperatures in your kitchen. This makes them very hard, and because of that, brittle. They can stand up to a lot of wear and tear, but a hard knock from a harder substance (like a hammer or tile floor) will still crack them.
What is needed for nitrogen oxides to be produced when hydrocarbon fuels are burned?
very high temperatures
Why a clinical thermometer crack in hot water?
A clinical thermometer may crack in hot water due to rapid expansion of the glass material when exposed to extreme temperatures. The sudden change in temperature causes stress on the glass, leading to cracks or breakage. Additionally, if the thermometer is not designed to withstand high temperatures, it may not be able to handle the heat and crack.
Why would a car's dashboard crack when exposed to high temperatures?
High temperatures can cause the materials used in the dashboard to expand and contract, leading to stress on the surface. Over time, this repeated expansion and contraction can weaken the materials, eventually causing them to crack. Additionally, UV exposure can also contribute to the deterioration of the dashboard material, making it more prone to cracking.

Why does flammability of alkenes decrease?
the flammability of alkanes decreases as the hydrocarbon chains increase in length their evapouration rates decrease as longer chained molecules have higher boling points so temperatures must be high for them to evaporate therefore there is no fumes or vapours for longer chained alkanes at room temp like nonane and so on these hydrocarbons need higher temp to produce vapours n therefore will not burn with just a match

What temperatures do digital candy thermometers read ?
These thermometers need to be able to read super high temperatures. On average they will range from -40 all the way to 450 degrees F, You can also use an oil thermometer instead of a candy thermometer sine the temperatures needed for both can be very high.
