Which is faster Heat অথবা Cold? Explain ?

Sex. Because it's the answer to everything.

Definitely heat. It is easily transferred through metals and as the metal heats up it will also give off heat. Cold is slower than heat. When it comes through metal, It tends to "frost" the metal and not give off near the same amount of cooling that it would if it were heat going through the pipe

Heat, I go fast and so does my hotness :J

Heat travels. Cold doesn't. Heat is radioactivity whereas cold is the lack of heat.

Heat, because আপনি can catch a cold.

Heat is the one that travels
Cold is a lack of heat
Heat travels from warmer objects to শীতল ones :3

I am too tired and lazy to give a scientic definition, besides, not my forte... but I would say Heat. Something can heat up (not boil) just heat to be white hot almost instantly. Flame can be produced instantly. Cold creeps. (unless we are taking liquid nitrogen & then I don't know my theory might be blown!)

I heat up faster XD
