Why do thermometers never agree?

That's precisely what he just said.

I don't need to use my hands for that.

And the thermometer actually comes back out unharmed?

I'm not admitting to that in public.

No it ISN'T what he said. He said HEAT rises.

It doesn't. If it did, how would the heat of the Sun ever reach us ?

Not with one of grandfathers cows. Newly qualified vet 'lost' the thermometer when cow suddenly belched.

Yes.

yes I know.

Hot tea rises too, and cold tea would sink.

yes via convection in the case we are talking about.

But if someone is walking around the room then that too would change things and perhaps conduction would play a small part.

I never mentioned all of it.

Is that an excuse ? I thought everyone knew that hot air rises and cold air falls didn't realise you needed a degree in thermodynamics.

after a time and with working senses then yes, it happens to me. When I get home it feels really warm compared to outside temps. Typcailly 11C outside 21C inside. Aftere a while IO start to feel cold so put the heating up higher.

exactly

But it makes you sweet, which means water on yuor skin which evapourates taking the higher temperature with it.

Heat as in the substance that is hot, heat gets transfered this way. Hot is an arbitary definition and needs more explaining as ice can be hot compared to liquid nitrogen, but we dontl; normlly call ice hot even if it is hot.

there are 3 ways heat 'travels' heat from the sun doesn't use hot air and rises means little when talking about space, because of gravity.

You're just being childishly pedantic. Heat rises through convection. Obviously this only applies if there's movable liquid or gas. Do you really need people to spell everything out precisely for you?

I'd be more concerned for the cow, with a now smashed glass thermometer with mercury inside it. Or are animal ones non-toxic and biodegradable?

Where I am, it's usually dry in the winter (although summers are usually very humid). When we do have a humid day in the winter, it's much colder for that temperature.

The day I took my grandmother to a hospital in another city, the weather was like that. I had to use the A/C, but being cold was preferable to not being able to see.

That makes more sense that way round - damp air will conduct more body heat away from you. But in summer, damp air prevents evaporation from sweat. In other words, humidity always makes extremes feel moreso.

Still wrong. Warm air rises because it expands and it is lighter than colder air surrounding it. Basic physics.

then your A/C is wromgly set. It can dry the air and keep you warm at the same time. My last few cars have all been able to do this.

Which is what we both said. The air carries the heat upwards. You shove a load of heat into the air at the bottom of a tall room, and it ends up at the top. Ergo, the heat has risen.

Everybody since the dawn of mankind has said "heat rises". That doesn't mean it's true in every case, it doesn't rise up a steel rod for example. Welcome to the English language....

So why does the atmosphere get colder the further up you go? :-)

Because there are many more ways heat can move. My c*ck is warmer than my finger, explain that.
