Which of the following is the best example of transforming electromagnetic energy into thermal energy?
A. when trees absorb sunlight for photosynthesis
B. when the interior of a car absorbs sunlight and warms up
C. when a solar panel absorbs sunlight to make electricity
D. when a newspaper turns yellow from sitting in direct sunlight
my answer- C or whatever. Please tell me why if its wrong!!! or please tell me why it is correct if it is correct...
C is the opposite of what you want. The solar panel takes EM energy and makes electricity just as the statement says.
I think B is what you're looking for. You are taking the EM energy from the sun, it goes through the glass of the car and is absorbed. The interior of the car gets hot. You have transformed EM energy (infrared, uv, visible, etc) into heat.
The correct answer is B. When the interior of a car absorbs sunlight and warms up.
When trying to determine which option is the best example of transforming electromagnetic energy into thermal energy, we need to consider how electromagnetic energy is converted into heat. In this case, sunlight (which is a form of electromagnetic energy) is being absorbed by an object and transformed into thermal energy, or heat.
Let's go through each option to see which one fits this description:
A. Trees absorbing sunlight for photosynthesis - Trees do absorb sunlight, but this process is mainly used for photosynthesis, where the energy is converted into chemical energy, not thermal energy.
B. The interior of a car absorbing sunlight and warming up - This is the best example because the car's interior is absorbing the sunlight and converting it into thermal energy, leading to an increase in temperature.
C. A solar panel absorbing sunlight to make electricity - Solar panels convert sunlight into electrical energy, not thermal energy.
D. A newspaper turning yellow from sitting in direct sunlight - This is more of a color change due to exposure to sunlight, and not really an example of electromagnetic energy being transformed into thermal energy.
So, option B is the correct answer as it clearly represents the conversion of electromagnetic energy (sunlight) into thermal energy (the heated car interior).
