@bo_ptah@Joe_The_Cow@amazing_physics Heat is not created. It's the measure of thermal energy in a mass. That's all it is. If the energy is transmitted and absorbed, the heat will increase. Nothing is created. A particle that has thermal energy radiates it as well. Sum in smaller than sum out? No melting.
@bo_ptah@Joe_The_Cow@amazing_physics The heat isn't created. It's transferred. 100j sent. 50 j absorbed. The mass radiates 50 J away. Explain why it's impossible for a mass to radiate 50j of energy.
@bo_ptah@Joe_The_Cow@amazing_physics Heat is the thermal energy of the mass. 100j was shined at it. 50J was reflected. 50J was converted to thermal energy/heat. But 50J is also radiated by the mass over the same time. Net zero increase in thermal energy/heat. No increase of heat, no melting temp, no melting.
@MiskelWilliam@fire_starter457 Right? I say the same thing about couples where the dude is sterile. Like how dare they live that lifestyle without having kids. No mentoring. No sacrificing. Etc.
Different lifestyle.
@AlexAlvzSlz9@downbadcomment Babysitting is not a task you do with the other person. It's something you do for them. The same way her asking him to cook her dinner is not the same thing as suggesting cooking dinner together.
@bo_ptah@Joe_The_Cow@amazing_physics Sorry I clarified about but I guess you need more. 100 sent. 50 absorbed in. 50 reflected out. 50 radiated out. 50% efficiency for radiation from the overall source.
@bo_ptah@Joe_The_Cow@amazing_physics No all 50j has turned into heat in my example when it was absorbed. That process continues, but is countered by the thermal energy being converted into radiation and leaving the mass. 50j in 50j out. No net thermal change. No melting.
@bo_ptah@Joe_The_Cow@amazing_physics Sure. Now tell me this. Why does the material need to emit thermal radiation at 100% efficiency? If it absorbs 50J it only needs to get rid of 50J. If the light shines on it sent 100j of energy, you only need 50% efficiency to break even.
@bo_ptah@Joe_The_Cow@amazing_physics Only impossible to the brainless. You can do it at home if you want. Hang a block of metal in a vacuum chamber by a poor thermal conductor. Then shine a flashlight at it. Be sure to hold your breathe until it melts. Will do the whole world a favor.
@bo_ptah@Joe_The_Cow@amazing_physics Some energy is reflected. The energy that is absorbed heats the material and has to be mitigated. It's mitigated by thermal radiation. A form of heat transfer that works in a vacuum.
@bo_ptah@Joe_The_Cow@amazing_physics Oh well lucky for the block it is shining with the same intensity. Infrared radiation, visible light reflection, and all other measures of thermal radiation. With the net result of the object not melting. Neat huh?
@bo_ptah@Joe_The_Cow@amazing_physics Heat is the thermal energy of a mass. Heat transfer is moving that energy from to another mass. Done via the 3 methods: conduction convection and radiation. Radiation is heat transfer. And radiation works in a vacuum. You're just wrong. No amount of pedantry is saving you.
@bo_ptah@Joe_The_Cow@amazing_physics Block of metal inside a vacuum, with a flashlight on it, is not going to melt. The characteristics of the material determine how it responds. The same way 2 colors of cloth take on different temperatures from the same heat source. You're ignoring reflection entirely.

@bo_ptah@Joe_The_Cow@amazing_physics It doesn't need to. It just needs to mitigate as much energy as it receives. 100j in from radiation. 50 not absorbed from reflection. 50 radiated away. No 100% efficient heat transfer. Still no net increase in heat.
@bo_ptah@Joe_The_Cow@amazing_physics 'thermal energy' means energy relating to caused by or being produced by heat. And heat is characterized by the transference of thermal energy. But heat transfer and thermal transfer are 2 separate things to you?
@bo_ptah@CatinNextLife@Joe_The_Cow@amazing_physics They as in the person you responded to dumb fuck. I don't know if they are male or female. They is the neutral term. I'm not shocked grammar also eludes you.
