Question

When you eat cereal and thenlift weights, how is the energytransformed?A. The chemical energy in the cereal istransformed into mechanical energy.B. The thermal energy in the cereal istransformed into mechanical energy.C. The mechanical energy in the cereal istransformed into chemical energy.

Answer 1

in any food not just in cereal there are chemical energy is stored in the form of

carbon, protein, fats, etc.

when we eat the food our body transforms this energy into

energy by decomposing the food into its elementary

particles and store it in the form of chemical energy and when we need energy

to do work it (body) coverts the energy into the mechanical energy by various

process.

so the correct answer is option (A)
