Richard 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 6minutes.

Question

Salmon Initial temperature (°C) Final temperature (°C)
Salmon on the right half of the grill 25 54
Salmon on the left half of the grill 25 44

during this time thermal energy is transferred from ? to ?
each salmon... the surroundings
the surroundings... eat salmon

Answer 1

During this time, thermal energy is transferred from the charcoal in the grill to each salmon. The thermal energy is being absorbed by the salmon as they cook, causing their temperatures to rise. Specifically, the salmon on the right side of the grill is absorbing more thermal energy than the one on the left side, leading to a higher final temperature.

In terms of the options you provided:

1. Each salmon... the surroundings - This is incorrect, as the salmon are gaining heat from the grill, not losing it to the surroundings.
2. The surroundings... eat salmon - This is also incorrect; the salmon's heat is not being transferred to anyone eating them.

The correct understanding is that the thermal energy is transferred from the heat source (the grill/charcoal) to the salmon.
