Conduction is the process of heat transfer through direct contact between materials. Based on the scenarios provided:
1) You walk barefoot on a hot street, and it burns your toes - This is conduction, as the heat from the hot street is directly transferred to your skin through contact.
2) When you get into a car with hot black leather in the middle of the summer, and your skin starts to get burned - This is also conduction, as the heat from the hot leather is transferred to your skin upon contact.
3) A flame heats the air inside a hot air balloon, and the balloon rises - This describes convection, as the hot air rises due to being less dense, rather than direct contact heat transfer.
4) A boy sits to the side of a campfire he is 10 feet away but still feels warm - This is radiation, as heat travels through electromagnetic waves from the fire to the boy.
Given the analysis, the correct answer is:
**A) 1 and 2**.
