Randall D. Knight β Work, Heat, and the First Law of Thermodynamics: Problem 35
You are boiling pasta and absentmindedly grab a copper stirring spoon rather than your wooden spoon. The copper spoon has a 20 mm \(\times\) 1.5 mm rectangular cross section, and the distance from the boiling water to your 35Β°C hand is 18 cm. How long does it take the spoon to transfer 25 J of energy to your hand?
π Solution Approach
Given: 20 mm, 1.5 mm, 35Β°C, 18 cm, 25 J
