Explanation:

1.

Heat flows from a warmer object to a cooler one. The drink is warmer than the ice, so heat flows from warm (drink) to cold (ice).

Central heating systems distribute heat in a house mainly through convection (movement of heated air). Conduction is more for direct contact, while convection circulates warm air.

When mixing equal amounts (1 cup each) of 150°F water and 50°F broth, the final temp is the average: $\frac{150 + 50}{2} = 100^\circ\text{F}$.

Step1: Calculate average temperature

$\text{Final Temp} = \frac{150 + 50}{2}$

Step2: Simplify the expression

$\frac{200}{2} = 100$

Answer:

warm to cold
