AI Thread Summary
In an experiment with two identical cans, one black and one white, filled with equal masses of water and exposed to the same power of radiation, the water temperatures will not reach the same level. The black can absorbs more heat due to its color, leading to a higher temperature than the white can. This difference in absorption suggests that the initial temperature of the water in both cans may not have been the same. Even after sufficient time, the black can's water could reach a temperature of 50 ºC while the white can's water may not reach that temperature under identical conditions. Therefore, the color of the can significantly affects the final water temperature.

Suppose the following experience:
Two identical cans one black and one white with equal mass of water inside.
We focus radiation at the same power on each.
After enough time, that we want, do the water will reach the same temperature in both cans?
If not, can we conclude that the water was at different temperatures in the cans at the beginning of the experiment?

Please explain what you mean by this.
 
Suppose that the water in the black can goes to 50 ºC. Is it possible that the water in the white can goes to 50ºC, if we gave it enough time, maintaining same initial conditions?
 

Thread 'Basic thermal energy transfer physics: Insulation value in open airways vs sealed airways'

Been around 40 years since I took basic physics in college and while I remember doing some examples of insulation values / energy conduction, I doubt I could to the math now even if I could find the formulas. I have some some corrugated plastic sheet (think of the plastic signs you see on the side of the road) that is used in bee hives. Also have some used in a green house though a bit different in dimensions than this example but the general approach should still apply. Typically, both...

Thread 'Using battery energy to heat a battery…'

Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...

Thread 'Is Callen right in claiming dQ=TdS for all quasi-static processes?'

Hello! I am currently reading the second edition of Callen's Thermodynamics and an Introduction to Thermostatistics, and I have a question regarding Callen's definition of quasi-static. On page 96, Callen says: Another way of characterizing Callen's definition is that a process is quasi-static if it traces out a continuous curve in the system's configuration space. So far it's all well and good. A little later, Callen claims that the identification of $$TdS$$ as the heat transfer is only...
