a: temperature ~
b: voltage

What:

"There is also an electrical analog which may help - temperature is like voltage; heat is like amperage.

Or a fluid analog - temperature is like pressure; heat is like flow.

Heat was originally believed to be a fluid, flowing from high temperature material to low temperature material. This fluid idea is incorrect, as they later realized. However, it may help somewhat to use the idea for basic purposes."

a: Temperature ~
b: wall builders

What:

"Temperature is like the height or reach of the wall workers - with heat transfer, once two objects are the same temperature, they no longer transfer heat. Similarly, as the wall gets higher, it becomes harder to add bags to it. Eventually the wall will be tall enough that the workers can't reach high enough to add any more bags. If food is uniformly the same temperature as its surroundings, no heat transfer will occur (although chemical reactions will still be occurring, so 'cooking' may still be happening."

a: temperature inversion ~
b: putting a lid on the saucepan

What:

"A layer of cold air sinks down close to the ground and gets overridden by warm air," Jeffrey said. That's kind of like a saucepan that you pour water in. You turn on the burner and it starts to boil. On a good day, that steam or pollution goes up and drifts away. But a temperature inversion is like putting a lid on the saucepan. The pollution builds up and the air just gets dirtier and dirtier. A lot of what you're seeing that you think is fog is really air pollution."

a: temperature inversion ~
b: lit cigarette in a bowl

What:

"Meteorologist Joe DeNardo said that temperature inversion is like putting a lit cigarette in a bowl and then placing a blanket on top of that; the smoke continually fills up the bowl and has no way of escaping. Temperature inversions were not unusual for Donora, but this one was different because it lasted for five days."
