Amanda just poured herself a cup of hot coffee to get her day started. She took her first sip and nearly burned her tongue. Since she didn't have much time to sit and wait for it to cool down, she put an ice cube in her coffee and stirred it with a metal spoon. After a moment, she felt the spoon warm up, but when she took another sip, the coffee was cooler. She was pretty sure, the ice added cold to her coffee, and the coffee added heat to her spoon.
Would you agree?
