<span>The answer is A. This is because sunlight is composed of various wavelengths in the
electromagnetic spectrum. In the visible
light spectrum, red light has a higher frequency
(lower wavelength) than blue light that has a lower frequency (higher wavelength).
Therefore red light has higher energy than blue light hence able to penetrate
more into the atmosphere before scattering, compared to blue light. At sunrise
and sunset, due to the relative angle of
the sun to the observer, the sun rays
have to penetrate a thicker layer to the atmosphere
before reaching the observer</span>
Answer:
Answer: II and IV
Explanation: Flammability and the ability to rust are chemical properties because they change an object. I, III, and V are physical properties because it doesn't change the object's composition. This includes weight, the change in matter (solid to liquid), or change in volume.
Hope this helps!!!
Explanation:
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere. Photosynthesis is part of the carbon cycle, and cellular respiration is not. (Only plants perform photosynthesis, and only animals perform cellular respiration )
Explanation:
Answer:
higher temperature → more kinetic energy → more space between particles higher volume
Explanation:
Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature is directly proportional to the average kinetic energy of gas particles.
The following sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory:
higher temperature → more kinetic energy → more space between particles higher volume
