  • Thermo Question

    A basic thermo question on a job intervew I got once went like:

    You are standing at a coffee shop across the street from your office on a cold day. In one hand you have a hot cup of coffee and the other the cold creamer. You will exit the coffee shop and return to your office. Your mission is to reach your desk with the hottest cup of coffee possible. Do you:
    1) Pour the creamer into the coffee before you leave the coffee shop?
    2) Carry the creamer and coffee separate and combine at the office?

    Travel time is negligible. You cannot throw away the creamer, it must go in the coffee. Temperature difference is academic; assume shop and office room temp and outside significantly below room temp.

    So what's the answer?
