Depends on how hot the tap water is. Cold water boils faster than room temperature water. Water that is already hot will of course hot boiling temperatures faster.

You've confused your weird science facts

Hot water turns to ice faster than cool/room temperature water.

[Anonymous No.10168400]

Americans only get 110 volts so boiling water means you have to plan a few days ahead.

[Anonymous No.10168540]

>>10168397
And you are confusing science with dad science.

Hot water does not freeze faster. What happens is hot water evaporates faster leaving less water to freeze.

Plumbing codes have specified copper pipes for hot water for well over a century. Lead was only supposed to be used for cold water.

>>10168400
>Americans only get 110 volts
Wrong. We have both 110 (actually 120) and 220 (actually 240) in our houses, on separate circuits. The service lines to the breaker panel are 60Hz 240V split-phase. Most outlets are 120V single-phase, but there are always a few outlets wired for 240V to accommodate major appliances (including an electric range if you're so unfortunate as to not have gas service).

>>10170048
Who uses an electric kettle when they have a perfectly serviceable gas range?

Also, who uses an electric kettle to boil water for pasta?

I remember learning about molecules, and how they spread with heat to make gas, and condense with cold to make ice.

I never learned what makes water boil faster.

Once it gets to the same temperature as the hot water it takes the same amount of time to reach boiling, so no, it doesn’t heat faster.

There is no such thing as inertia in heat flow.

[Anonymous No.10175032]

Sometimes, when I have to heat a lot of water for boiling, I heat some of it on my electric range and as much as possible in my electric kettle, the pour the water from the kettle into the pot when it is boiling. That way I have at least double the power input. This reminds me that one of those days I'll have to get a 3000W kettle instead of the ordinary 2000W ones. My last holiday apartment had one of those, it was great.

[Anonymous No.10175428]

>>10168159
The phenomena you mention does exist in very specific (basically lab) conditions but in practice hot water heats up to a boil slightly quicker or about the same as cold.
Its one of those things that's technically true, but misconstrued by pop-science classroom nonsense.

However it's still best to use cold water so it doesn't put contaminants in your boiling water.

[Anonymous No.10176231]

>>10176220
>contaminants
You're retarded
American hot water pipes have been copper for over a century, only some older cold water pipes are lead
Your tap water is more likely to be contaminant free if you get it hot in the US
stop being a retarded bong who still has lead pipes from the 1600s

[Anonymous No.10176257]

I can't tell you the science behind why that sounds stupid, because I don't know. What I do know is that in my life time it always takes fucking 10 minutes of the sink running for the water to start coming out hot. In that time I could have boiled two pots or water.

You're a fucking dumbass, even copper pipes will have certain dissolved minerals that hot water more readily picks up.

Hot water sometimes (partially) freezes faster than cold water, but it requires a very finely tuned set of conditions for that to happen.

https://en.wikipedia.org/wiki/Mpemba_effect

The inverse Mpemba effect that OP describes may be possible, but it requires that the heated systems are out of equilibrium, which is not the case for tap water.

[Anonymous No.10177779]

Maybe it's because my dad is an HVAC engineer, but I can't imagine being so ignorant as an adult that you don't understand the relationship between heat and boiling.
