Energy does / does not change the phase of matter.

does

Explanation:

the bubble appears DARK

Explanation:

This problem shows the interference by reflection of light on the surface, let's take it into account;

* There is a phase change of 180º on the surface when it stops from a lower medium to a higher index

* Within the film the wavelength changes due to the fraction index

if we plug this into the expression for constructive interference we have

       2tn = (m + ½) λ₀

for destructive interference it is

       2tn = m λ₀

apply these expressions to our case

indicate that the incident wavelength is red λ₀ = 700 nm

Let's find the minimum thickness that the film must have to have a constructive interference

the refractive index of soap is n = 1.4

from the constructive interference equation

            t = (0+ ½) 700 10⁻⁹ / 2 1.4

            t = 1.25 10⁻⁷ m

just before the soap bubble explodes the thickness (t) of the film less than the calculated value there is no possibility of constructive interference, therefore the bubble appears DARK

When a snowball turns into a puddle of water, we know that (the snow ball gains energy and changes from a solid to liquid).

This is correct due to the fact that particles of the snowball are gaining speed and so it is heating up, when the solid's temperature reaches the melting point, it will become a liquid.

Therefore, D is the correct answer.

Matter cannot be created or destroyed.

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same

Or

Conservation of mass means:

In a closed/isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

So what changes is the form, into a liquid, gas or solid

while what does not change is the mass

1) Four daughter cells are produced in the process of meiosis.

2) Genetic makeup and environmental condition are the factors that contribute to the variety of traits amongst family members.

3) Down syndrome is a type of disorder in which one extra copy of chromosome is present in the daughter cell while turner syndrome is a type of disorder in which one chromosome is absent in the daughter cell.
