Theo mixes cake batter and places it in the oven at 350°F
for 45 minutes. Explain what type of reaction baking a
cake represents in terms of energy.

Endothermic reaction

Explanation:

Baking a bake batter in an oven is a typical endothermic reaction because it absorbs heat to drive a chemical change.

The heat changes that accompanies a chemical reaction can be categorized as either exothermic or endothermic.

In baking a cake batter, the oven furnishes it with a high temperature which drives a chemical change there in. This kind of reaction that absorbs energy from the environment is an endothermic reaction.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
