Rank these photons in terms of increasing energy:<br> (a) blue (λ=453nm)
alexira [117]

The increasing order of photons in terms of energy is Er < Ey < Eb

A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.

By using the formula:

E = h * ν

E = h * c / λ

h = planks constant

c = speed of light

Since h * c is constant

E is inversely proportional to wavelength  λ

For blue:

λ = 453 nm

Eb= k / 453

where k is constant

For red:

λ = 660 nm

Er = k / 660

For yellow:

λ = 595 nm

Ey = k / 595

Therefore,

The increasing order of photons in terms of energy is

Er < Ey < Eb.

True or false, The ideal gas lead allows us to figure out a fourth variable about a gas when the other 3 are given
klemol [59]

Answer:

true

Explanation:

PV=nRT

The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant R is called the Boltzmann constant

Which substance is an example of plasma? Question 3 options: Air Blood Lightning Wood
pychu [463]

Answer:

Q 3 = lightning

Q 4 = False because there is also a fourth state of matter which is called plasma.

Q 5 = most of the matter in universe is made up of plasma.

Explanation:

Plasma:

" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"

The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.

It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.

Examples:

The shining stars, lightning bolts, fluorescent light, flames, electrical current which passes through neon gas are some examples of plasma.
