C. It stays the same as energy is added.
Answer:
Explanation:
What do gases consist of?
Gases consist of small particles that have mass.
What evidence does this reading give that gas particles have mass?
An inflated basket ball weighs more than a deflated basketball therefore, particles must have a mass.
Why can gases be compressed easily but not liquids and solids?
The gas molecules are separated from each other by relatively a large distance. The space between the particles allow them to be pushed closer together. Liquid and solids can not compressed easily because particles are packed tightly.
Why can gases filled their container completely but not solids?
The particles of gas must be on constant rapid motion. Because of this motion gases immediately fill their container. These rapid moving particle can mix easily with each other so that gas released at one end of container quickly diffuse to other end.
What is the collision?
The particles of gas are on constant rapid motion. Because of this motion gas molecules colloid with each other and also with the wall of container. When they strike with each other and with the wall this is called collision.
What does reading compare gas particles to?
This reading compare the gas particles with the rubber balls in a empty room.
According to reading how gas particles are differ from rubber balls?
The balls strike with each other and also with the wall and hence their motion slow down but in case of gas particles their motion can not slow down on collision. Because of it is happens then gas convert in to the solid or liquid. That's why it is not happen in case of gas molecules.
Answer:
NBr3 has a trigonal pyramidal geometry where the nitrogen atom is bonded to three bromine atoms and has one lone pairs. The individual bonds are polar, as bromine is less electronegative than nitrogen. The overall compound is also polar, as the dipoles do not cancel.
Explanation:
Answer:
By absorbing energy electron is jump into higher energy level. This is called excitation.
Explanation:
The electron is jumped into higher level and back into lower level by absorbing and releasing the energy.
The process is called excitation and de-excitation.
Excitation:
When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits. For example if electron jumped from K to L it must absorbed the energy which is equal the energy difference of these two level. The excited electron thus move back to lower energy level which is K by releasing the energy.
De-excitation:
When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.
The amount of W : = 1.22 x 10²⁰
<h3>Further explanation</h3>
Given
5.6 mg of a micro computer
Required
The amount of chip
Solution
A mole is a number of particles(atoms, molecules, ions) in a substance
1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mass = 5.68 mg = 5.68 x 10⁻³ g
mol :
= mass : MW
= 5.68 x 10⁻³ g : 28 g/mol
= 2.03 x 10⁻⁴
The number of atoms :
= 2.03 x 10⁻⁴ x 6.02.10²³
= 1.22 x 10²⁰
