What is the relationship between the energy released by the Cheeto and the energy absorbed by the water in the Cheeto Lab? Choose the best answer.
All the energy that went into the water came from the Cheeto
All the energy from the Cheeto went into the water.
The energy that the water absorbed is different than the energy that was released by the Cheeto. The energies are not related.
