Line In The Sand!!!!!

I liked IT as well back in the 80's one of my submarines was my favorite from the album

So, I take it you graduated HS in say 1985 or so? My guess is you are in your early 40's? Just curious is all. I remember this song being so cool with such a lame video. I just could not get enough of it. Glad to hear you liked it as well.

Cheers,

Phil

Yeah what he said ^^^^^^^^. So glad I am done with science because it blinded me in more ways that one.

Ever put your hand on a compressor's tank after it pressurized it? Same principle. More pressure, higher temperature (more heat). Remember- temperature is an indication of average molecular velocity and if you ask why I remember this, it's because I have a freakish memory.

I'm a sick puppy.

Interesting example. However, science is really not my thing. My favorite was always lunch-still is............Lmao!!!!!!!!

Pop quiz - is heat transferred from an object with a lower temperature to one with a higher temperature?

I know I know oh please select me...........Lmao!!!!!

The quiz is open to the whole class, Phil.

From higher to lower.

 

[Adam]

From higher to lower.

So is your answer "no"?

 

[Rickster71]

So is your answer "no"?

If confined to a yes or no, I would say no.
Heat moves from the hot source to a colder one.

 

[speakerman39]

Heat always moves/tranfers from a greater temp to lesser temp. As such, the answer is no. It is the other way around than the way you posed the question.

Heat does indeed move from an object with a higher temperature to one with a lower temperature. So, you're right on that. However, it also goes the other direction, too. So, the answer is actually "yes."

Hey Phil, do we get a prize or anything?

 

[Adam]

That's not it at all! It was not entirely a trick question, but it was one that most people aren't going to get. The net rate of heat transfer is from hot to cold, and that's what almost everybody learns.

 

[Rickster71]

However, it also goes the other direction, too. So, the answer is actually "yes."

What would be an example of that?

 

[Adam]

What would be an example of that?

The easiest example is radiation. Your body is emitting heat as radiation to everything around it - things that are hotter and things that are colder than you. The same is true for everything around you. Your walls are probably cooler than you, but they are radiating heat to you.

 

[Rickster71]

Interesting. Thanks Adam

Well I'm going to bed, I can't stay up with the big boys.

Happy Easter all.

 

[Adam]

Have a good night, Rick, and Happy Easter to you, too!

Hey Phil, do we get a prize or anything?

Yep, just for trying.........Lmao!!!!!

It is the only thing I remember from Chemistry in HS. Believe it or not, I was not always an ANGEL..............Lmao!!!!!
