Question

lesson 24: systems and energy
you walk into a room and you start to feel cold. if you are the system, which of the following is true? (select all that apply)

• an exothermic process is occurring
• an endothermic process is occurring
• you are absorbing heat
• you are losing heat

Explanation:

• An endothermic process is when the system absorbs heat. Since you (the system) feel cold, it means you are losing heat to the surroundings. Losing heat from the system is an exothermic process from the system's perspective (heat is going out of the system).
• Absorbing heat would make you feel warmer, which is not the case here.

Answer:

an exothermic process is occurring, you are losing heat
