Describe the conditions under which a real gas is most likely to behave ideally
Answers
Answer:
- The conditions under which a real gas is most likely to behave ideally is at low pressure and hight temperatures.
Explanation:
According to molecular kinetic theory, 1) gas particles (molecules or atoms) occupy a negligible fraction of the total volume of the gas, and 2) the force of attraction between gas molecules is zero.
Those two assumptions constitute the basis for the behavior of a gas and an ideal gas.
The lower the pressure and the higher the temperature the closer those assumptions are valid for real gases.
At low pressure, the particles of the gas will be more separated from each other and so the tiny volume they occupy will be a smaller fraction of the total volume.
At higher temperatures, the particles will have more kinetic energy, which means that they will have larger average speed, and so the forces between the molecules will count less.
So, you conclude that under low pressure and high temperatures a real gas is most likely to behave ideally.

The light-gathering capacity of a telescope is dependent upon the:
magnification
focal length
size of human iris
area of aperture
Answers
Answer:
1) blue end of the spectrum
2) area of aperture
Explanation:
1) The electromagnetic spectrum encompases a wide range of frequency (ν) and wavelength (λ) that includes gamma rays, x-rays, ultra violet(UV), visible, infra red (IR), microwaves and radiowaves. The wavelength increases from gamma rays to radio waves.
The wavelength perceivable by human eyes lies in the UV-visible region which extends from 380 nm in the blue to 740 nm in the red.The shortest wavelengths occur in the blue end of the spectrum which also have the highest energy. In contrast, longer wavelengths occur on the red which have lower energy.
2) The light gathering capacity of a telescope is dependent upon its area of aperture. Larger the area, greater is the light gathering power which implies that the telescope has the capability of detecting weak or faint objects.
The area of the aperture is essentially the area of the objective of the telescopic lens which is given as:
where D = diameter of the lens
1) blue end of the spectrum
2) area of aperture

Features which are found in plant cellsonly are the chloroplast, large vacuole and cell wall.
- Plants and animal cells consists of the following parts ; Mitochondria, cell membrane, vacuole, cytoplasm and so on.
- The vacuole present in animal cells are much smaller than those found in plant Cells. Hence, vacuole in animal cells are called small vacuole
- Plant cells also consists of cell wall, chloroplast and a large vacuole. All these are missing in animal cells.
Therefore, Only plant cells have "acellwall,chloroplastsandalargevacuole."

Answer: .1044 J/g*C°
Explanation: The equation you need to use for this problem is :
c= q/m* ΔT
We are given
T1= 27.1 C°
T2= 145 C°
M= 34.87g
1071 J absorbed heatt
So let's solve specific heat
c= 1071J/ (87grams)*(145 C°- 27.1 C°)
c= 1071J/10,257.3 g*C°
c= .1044 J/g*C°
c=specific heat

This hypothetical process would produce actinium-230.
Explanation
An alpha decay reduces the atomic number of a nucleus by two and its mass number by four.
There are two types of beta decay: beta minus β⁻ and beta plus β⁺.
The mass number of a nucleus stays the same in either process. In β⁻ decay, the atomic number increases by one. An electron e⁻ is produced. In β⁺ decay, the atomic number decreases by one. A positron e⁺ is produced. Positrons are antiparticles of electrons.
β⁻ are more common than β⁺ in decays involving uranium. Assuming that the "beta decay" here refers to β⁻ decay.
Gamma decays do not influence the atomic or mass number of a nucleus.
Uranium has an atomic number of 92. 238 is the mass number of this particular isotope. The hypothetical product would have an atomic number of 92 - 2 ⨯ 2 + 1 = 89. Actinium has atomic number 89. As a result, the product is an isotope of actinium. The mass number of this hypothetical isotope would be 238 - 2 ⨯ 4 = 230. Therefore, actinium-230 is produced.
The overall nuclear reaction would involve five different particles. On the reactant side, there is
- one uranium-238 atom.
On the product side, there are
- one actinium-230 atom,
- two alpha particles (a.k.a. helium-4 nuclei),
- one electron, and
- one gamma particle (a.k.a. photon).
Consider: what would be the products if the nucleus undergoes a β⁺ decay instead?
