Question

Two beakers of water, A and B, initially are at the same temperature. The 

temperature of the water in beaker A is increased 10 F°, and the temperature 

of the water in beaker B is increased 10 K. After these temperature changes, 

which beaker of water has the higher temperature? Explain.

Answer 1

Find the change in temperature in both bakers. The change of 10°F (say for water it is from 202 to 212°F) is equal to the change in Celsius of

$$\Delta t=((212-32)-(202-32))·5/9=5.56°\text{C},$$

while beaker B temperature rise was 10°C. So, B is hotter.
