When light travels between two substances it bends. This is called:

75% Answer Correctly

	convection
	refraction
	conduction
	reflection

Solution

Because different materials have different refractive indices, light changes speed when passing from one material to another. This causes the light to bend (refraction) at an angle that depends on the change in refractive index between the materials. The greater the difference, the higher the angle of refraction.

Which of the following represents the largest value?

61% Answer Correctly

	1 mL
	1 cL
	1 ML
	1 kL

Solution

Mega (M) is 10⁶, kilo (k) is 10³, centi (c) is 10^-2, milli (m) is 10^-3 so 1 ML represents the largest value.

63% Answer Correctly

	reactants
	components
	products
	fuel

Solution

During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
