.  What energy transformation takes place when you eat the pizza and then have energy to go run a mile?

When you eat a pizza, the process of digestion begins in your body. This process involves breaking down the food you eat into smaller molecules that your body can use. This is a form of chemical energy.

1. The pizza you eat contains chemical energy in the form of carbohydrates, fats, and proteins.

2. As you digest the pizza, your body breaks down these nutrients. This process of digestion involves a series of chemical reactions, and these reactions transform the chemical energy in the food into another form of chemical energy that your body can use. This is stored in the form of ATP (adenosine triphosphate).

3. When you start running, your body needs energy to move your muscles. It gets this energy from ATP. The stored chemical energy in ATP is transformed into kinetic energy, which is the energy of motion.

4. As you continue to run, your body also produces heat. This is because some of the energy from ATP is transformed into thermal energy. This is why you feel warm and may start to sweat when you exercise.

So, the energy transformation that takes place when you eat a pizza and then run a mile involves transforming the chemical energy in the pizza into chemical energy your body can use (in the form of ATP), then into kinetic energy (to move your muscles) and thermal energy (heat).
