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.

What fuses hydrogen to form helium?
Very high temperatures and pressures are needed to fuse hydrogen into helium.
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.

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 the volatility of Alkanes?
Alkanes high volatility as the type of Intermolecular Force of it is Van Der Waals', which is the weakest bond.
What is needed for nitrogen oxides to be produced when hydrocarbon fuels are burned?
very high temperatures
Does glass break or crack with temperature changes?
Glass can indeed break or crack when exposed to rapid temperature changes. This is because different parts of the glass expand and contract at different rates when the temperature changes, leading to stress within the material that can cause it to crack or shatter. This is why it's important to avoid sudden temperature changes when handling glass objects.
Why tungsten is used exclusively for making bulb filaments?
Tungsten is used for making bulb filaments because of its high melting point and low vapor pressure, allowing it to operate at high temperatures without quickly evaporating. It also has a high resistivity, meaning it can generate a significant amount of heat without breaking. These properties make tungsten ideal for producing bright and long-lasting light in bulbs.
What fuses hydrogen to form helium?
Very high temperatures and pressures are needed to fuse hydrogen into helium.
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
Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
