Question

which has the most thermal energy? the liquids are identical. 8 ounces of milk at a temperature of 55°f 14 ounces of milk at a temperature of 55°f 12 ounces of milk at a temperature of 55°f 6 ounces of milk at a temperature of 55°f

Explanation:

Step1: Recall thermal energy relation

Thermal energy depends on mass (amount) and temperature for identical substances. Formula: \( Q = mc\Delta T \), but here \( \Delta T = 0 \) (same temp), so \( Q \propto m \) (mass).

Step2: Compare masses

Masses: 8 oz, 14 oz, 12 oz, 6 oz. 14 oz is largest.

Answer:

14 ounces of milk at a temperature of \( 55^\circ\text{F} \)
