Do atoms recoil when emitting a photon?

[QUOTE="PeterDonis, post: 6847472, member: 197831"] How are you going to heat it up with radiation from a stove? If the air is at normal room temperature, that will melt the ice by conduction and convection, probably much, much faster than radiation anyway. A better example would be heating something in space, where it's vacuum so there is no conduction or convection. In a case where radiation is the [I]only[/I] source of heat present, then yes, you could say photons are adding kinetic energy, and therefore also linear momentum, to the atoms of whatever is being heated up. But that's one particular case. In the one particular case I described above, yes. But not in general, no. [/QUOTE]
