Question

walter lit the charcoal in his grill to cook two identical salmon. he put one fish on the left half of the grill and one fish on the right half of the grill. this table shows how the temperature of each salmon changed over 6 minutes.

salmon	initial temperature (°c)	final temperature (°c)
salmon on the left half of the grill	21	42

during this time, thermal energy was transferred from ____ to ____.

options:

• the surroundings . . . each salmon
• each salmon . . . the surroundings

Explanation:

The initial temperature of each salmon is 21°C, and their final temperatures (53°C for right, 42°C for left) are higher. Thermal energy transfers from a warmer object to a cooler one. Here, the grill (surroundings) is warmer than the salmon initially, so energy moves from the surroundings to each salmon, increasing their temperatures.

Answer:

the surroundings... each salmon
