Final answer:
Beaker B will have the higher temperature because a temperature increase of 10 K is greater than an increase of 10 F.
Step-by-step explanation:
The question asks which beaker of water, A or B, will have the higher temperature after beaker A's temperature is increased by 10 degrees Fahrenheit (F) and beaker B's temperature is increased by 10 kelvins (K). Since a temperature change of 1 K is equivalent to a temperature change of 1.8 F, a 10 K increase will result in a larger temperature change than a 10 F increase. Therefore, after these temperature changes, beaker B will have the higher temperature.
