4.)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 (I PICK THIS)
D.when a newspaper turns yellow from sitting in direct sunlight.
B?
Yes, you are correct. The best example of transforming electromagnetic energy into thermal energy is when the interior of a car absorbs sunlight and warms up (option B).
To arrive at the answer, you need to understand the concepts of electromagnetic energy and thermal energy. Electromagnetic energy refers to the energy carried by electromagnetic waves, such as sunlight. Thermal energy, on the other hand, refers to the energy associated with the motion of particles within a substance, which determines its temperature.
Option A, when trees absorb sunlight for photosynthesis, primarily involves the conversion of electromagnetic energy into chemical energy through the process of photosynthesis. This process is not primarily focused on thermal energy production.
Option B, when the interior of a car absorbs sunlight and warms up, is the correct answer. In this scenario, sunlight (electromagnetic energy) is absorbed by the car's interior surfaces, causing an increase in temperature (thermal energy). This is a clear example of electromagnetic energy being transformed into thermal energy.
Option C, when a solar panel absorbs sunlight to make electricity, is not primarily focused on transforming electromagnetic energy into thermal energy. Solar panels convert solar energy into electricity through the photovoltaic effect.
Option D, when a newspaper turns yellow from sitting in direct sunlight, is an example of light-induced chemical reactions, not primarily the transformation of electromagnetic energy into thermal energy.
