Answer:
hope it helps
Explanation:
Boiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.
Answer:
B
Explanation:
A is summer, C is winter, B should be fall in-between those 2
b. Refraction
Explanation:
Fish in the aquarium are looking much bigger than they are due to refraction.
Refraction causes the path of light to bend and the velocity and wavelength attenuated.
This phenomenon occurs when light travels between two materials of different densities.
- Air has a refractive index of 1
- Water has a refractive index of 1.33
- When light form water comes to air, the their angle changes.
- This causes the magnification of the fish.
