Thermodynamics in the kitchen (25 pts.) directions: to complete this activity, answer the corresponding questions completely the law of conservation of energy states that: "energy cannot be created nor destroyed. it can only be transformed into another form, with the total amount of energy remaining the same." the 1st law of thermodynamic systems. think, how is energy conserved when you eat breakfast in the morning? the chemical energy in food will be converted into mechanical energy that enables you to do work, like walking, running, and climbing stairs. but, not all chemical energy in the food you eat will be transformed into mechanical energy. some of it will be released from your body as heat, that is, when you sweat and feel warm. so you see, in the law of conservation of energy, we talk here of energy, work and heat. how are these three quantities related when we speak of thermodynamic systems? s is an extension of the law of energy conservation when applied to thermodynamic in thermodynamics, a system is any region completely enclosed within a well-defined boundary and ev- erything outside this system is considered its suttounaings. the system might be a biological organism, a mechanical device, or the whole of the earths atmosphere.
