Question

A very tired, very cold teacher filled her 500 g coffee mug with 1 L of hot coffee to help her warm up and get throw the day. Being the middle of winter, the mug was very cold, starting at 3.00 C. If the mug had a specific heat of 0.98 J/G C, and coffee has roughly the same specific heat as liquid water, what was the initial temperature of the coffee if the mug’s final temperature was 35.0 C?

Answer 1

Until temperature ,= $(35.0× 0.98)+3.00=37.3°C$
