Verified step by step guidance1
Understand the types of changes: Physical changes involve changes in state or appearance without altering the chemical composition. Chemical changes involve the formation of new substances with different properties. Mechanical changes involve physical forces affecting the object, and nuclear changes involve changes in the nucleus of atoms.
Identify the process: Cooking meat on a grill involves applying heat, which can cause changes in the meat's structure and composition.
Consider the effects of heat: Heat can cause proteins in the meat to denature and recombine, leading to new flavors and textures. This is indicative of a chemical change.
Evaluate the options: Physical change would involve changes like melting or freezing, which do not apply here. Mechanical change involves physical manipulation, which is not the primary process in grilling. Nuclear change involves atomic nuclei, which is not relevant to cooking.
Conclude the primary change: The process of cooking meat on a grill primarily involves chemical changes, as new substances are formed through the application of heat.
