How come we can see heat waves radiating off of hot surfaces but not like hot food?
In: Physics
Food loses heat through other means such as the sublimation of liquid to vapor. Also food isn’t as hot nor does it have a high heat capacity to continually feed the gas around it with enough heat to change the local index of refraction.
If you has a hot pizza that was the size of a road, you could see heat waves off it. To see them off a small slice of pizza, you’s have to get really close and they would still be pretty small. Size matters, in this case.
