Felipe 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.

During this time, thermal energy was transferred from ​​the​ ​ (a)   to the ​ (b)  

• surroundings
• salmon
