What type of energy change occurs when you bake a muffin in a oven?
Answer:
it's thermal energy, ex is out and en is in, it cooks from the outside in so it would be exothermic, if it were in a microwave it would cook from the inside out, endothermic.
Yeast in the muffin expands due to increase in temperature. The heat created by the rise in temperature causes molecules to move faster and create higher energy level: hence the reactions are both a endothermic and exothermic in that order.
Exothermic, it is receiving energy from another object.
