Reply to comment by Solarisphere in TIL Snow is an excellent insulator because it consists of about 90–95 percent trapped air (fresh). This is the reason why igloos are warmer inside than outside, and why some animals in colder regions build snow caves to spend the winter while hibernating. by SunCloud-777

wow dude, you just don't give up, huh. you picked a fight and your first sentence was wrong and you're back tracking.

"oh... well 'good' is a subjective measure"...

i said it was a bad heat conductor, and you took the opposite stance, and now you're trying to qualify your answer with completely different scenarios.

seriously man, i don't want to talk to you. this discussion happened yessssssterrrrday. you are a day 2 reddit twat that reads over comments and nitpicks them to death. ain't nobody got time for that.

i did address where you were flat out wrong, and then provided a scientific example as to why you were wrong. that you dismissed it, says all i need to know about this discussion with you.

> I don’t think there’s an agreed upon definition of “good” conductors.

heat conductivity is measurable, and predictable link

The unit of thermal conductivity, k = J/s⋅m⋅C°

there's a table listing some materials.

one of the really unusual characteristics of water is its low heat conductivity, which is a basis of its importance for life on earth... if water conducted heat more, it would freeze faster, potentially also from the bottom up, and global temperatures might swing too fast to support life. the same goes for ice and it's unique characteristics.

Yes there is an element of heat capacity and other thermodynamic terms going on... but i was keeping it simple for the person i was commenting to. if someone doesn't know why an igloo doesn't melt, it's easier to explain with terms they might know better.

water is not a good heat conductor, look it up.

edit: here's a link link

> In terms of heat conductivity, water is classified as a poor thermal conductor and acts as an insulator by resisting the flow of heat through it.

wow, this goes to show how much upvotes actually mean

every one of your comments in your comment history is argumentative, about stupid details and generally telling other people they are wrong.

you seem like a genuine asshole.

edit: omg that creep actually replied from an alt account just to get the last word in! hahahahaha

> Conductance refers to its ability to carry heat from a hot object on one side of it to a cold object on the other side

edit:

> It’s wrong to say that water (or ice) is a poor conductor of heat because it takes a lot of energy to melt it.

not what i said.

you basically said i was wrong, and then explained something else, said in other words.

i was trying to keep it simple. sure, it's not 100%. what i said is basically right, i explained in way that's easy to understand. unlike your explanation.

warm air inside the igloo does not conduct heat very well through the igloo material. if water was a better heat conductor, it would melt faster. many of the different thermodynamic properties are related to each other.

water is a poor conductor of heat, meaning you have to put a lot of energy (heat) against it to heat it up (or cool it down). So, ice "wants to stay ice".

this is why ice cubes work so well to keep drinks cool.

so, if you think about how easy it is to heat air up, and compare that to water... your igloo example starts to make a little more sense.

Reply to comment by Teledildonic in TIL Vincent Price published various cookbooks including a five volume series titled Mary and Vincent Price present a National Treasury of Cookery. Price promoted the cookbooks on TV shows including on the Tonight Show Starring Johnny Carson where he demonstrated how to poach a fish in a dishwasher. by trifletruffles

food isnt sterile. that's not the best metric to say one gross method of cooking is better than another.

Reply to TIL, there was a Cocaine-infused tablet called “Forced March” taken on the North Pole Expedition by Shackleton. As label explains: “Allays hunger and prolongs the power of endurance.” by endofthen1ght

i learned of Shackleton's trip, from Dan Carlin, where he mentioned it in blueprint for armageddon. what a crazy time in the world. Would love to read up more on Shackleton at some point.

what little i know, this TIL makes perfect sense considering the time period. haha
