Actually that math is correct. A change of 1 degree Kelvin is equal to a change of 1 degree Celsius. However, 0 degrees Celsius is equivalent to 273.15 degrees Kelvin. 273.15K +273.15K= 546.3 degrees Kelvin, subtracting 273.15 Kelvin converts back to Celsius. Since Kelvin refers to temperature relative to absolute 0, the combined heat of 0 C and 0 C would, in fact, be 273.15 degrees Celsius, equivalent to 546.3 degrees Kelvin.
Actually, it averages flowing from hot to cold. Veritasium had a really good video explaining this, and shows why energy can also flow from cold to hot, though it is less likely.
But it’s energy transfer so the scale is arbitrary and doesn’t matter. They don’t add. If you put two things the same temp together they maintain the temp longer, they don’t double. It’s like taking a voltage reading on two 24vdc terminals. It’ll be zero because there’s no potential.
This wasnt assuming putting 2 objects together, it was considering the equivalent amount of energy added to the same object. There are multiple ways to view this problem.
Also you can’t add temperatures like that without specifying what it is you’re adding. If you have one abject at 0 degrees and add another, there overall temperature will be the same.
However if you have an object at 0 degrees and double the energy in the object the temperature will rise proportionally.
This is why scales with an arbitrary 0 point are my favorite!
Interesting - Id never heard of ‘Scales’ Font before
No, 32 °F is not "equal" to 0 °C, it corresponds to 0 °C
0°C+0°C=273.15°C
No it's Kevin's not degrees. Not to be confused with Mikes

Except heat always flows from hot to cold, so it isn't addictive, it's averaged

Yeah, I asked that in my heat transfer class as well. The net flow is always hot to cold.

That was the assumption I was making. Adding the equivalent amount of energy to the same material.
Yea it’s congruent not equivalent
Or equivalent.
Were you not taught to normalize your units before doing arithmetic?
These jokes get a lot less funny after you find out what kelvin is.
0 K = -273,15°C 0 K + 0 K = -546,30 °C Works just as well!
Yeah, but Kelvin measures heat as a quantifiable amount of something. -546.3 C isn’t a real number, you can’t have a negative amount of oranges.
Negative -546 °C is a real number. It's just not an attainable temperature
Then why can you have beta values that correlate to negative values of Kelvin?
Everybody: thermometer funny 👹 Kelvin: 🥱 not funny, Steve. #Me: 🤣☝️☝️
But when you add temperatures (or any other quantities), you are actually adding T + dT. And if dT is 0C then 0C + 0C is 32F + 0F
Straight to heat transfer jail
Define addition here.
