Question

which has the least thermal energy? the liquids are identical. 24 ounces of salt water at a temperature of 90°f 32 ounces of salt water at a temperature of 90°f 20 ounces of salt water at a temperature of 90°f 14 ounces of salt water at a temperature of 90°f

Explanation:

Step1: Recall thermal energy relation

Thermal energy depends on mass and temperature (for same substance). Same temperature, less mass → less thermal energy.

Step2: Compare masses

Masses: 24 oz, 32 oz, 20 oz, 14 oz. 14 oz is the smallest.

Answer:

14 ounces of salt water at a temperature of \( 90^\circ\text{F} \)
