larger alkane molecules have strong intermolecular forces
Specified temperature, pressure and catalysts.

Its because Tungsten has a high tolerance to heat, they are also used in industrial saws and drills, because they don not crack at high temperatures.
Very high temperatures and pressures are needed to fuse hydrogen into helium.
I think it's because the covalent bonds are strong, and therefore unreactive to acids & alkalis. You'd need to get alkanes in gas form to make it react, but you'd still need energy for it to react, like, say, heat perhaps?

Temperatures can be very high endangering the spacecraft and the astronauts. Therefore, temperatures needed to be constantly monitored.
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.
Alkanes high volatility as the type of Intermolecular Force of it is Van Der Waals', which is the weakest bond.
very high temperatures
When temperatures changes this can cause the molecules in an object to contract [ at low temperatures ] or to expand [ high temperatures ] . Glass is a fragile object and if the molecules in glass contract or expand quickly this can cause the glass to break . [SRM] .

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
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
