What is the difference between light photons and infrared photons?
Answer:
Light Photons: Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more.
Infrared photons: Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.
On the electromagnetic spectrum, visible light has a wavelength that falls between 380 nm and 750 nm, whereas infrared light, which marks the beginning of the non-visible spectrum, has a wavelength that falls between 700 nm and 1 mm. Because of this, infrared can only be viewed with specialized tools like security cameras.
What is infrared light ?A type of radiant energy that we experience as heat, but that is invisible to human eyes is infrared radiation (IR), often known as infrared light. The sun and fire are two of the most prominent sources of IR radiation, however all objects in the cosmos release some of it.
The energy of the photons determines the various types of radiation, starting with radio waves with low energies. In comparison to visible, ultraviolet, X-ray, and gamma ray photons, which are the most energetic of all, microwave photons have somewhat higher energy. Infrared photons have even more energy.
Cooler objects produce lower energy, longer wavelength photons, while hotter ones release higher energy, shorter wavelength photons.
Thus, On the electromagnetic spectrum, visible light has a wavelength that falls between 380 nm and 750 nm, whereas infrared light.

How does the equilibrium change to counter the removal of A in this reaction? A + B ⇌ AB The equilibrium shifts left. Simultaneously, there's an increase in the reverse reaction.
Answer:
The increase in the reverse reaction
Explanation:
Based on the LeCh's principle, a change in the concentration of a species in the equilibrium will shift the concentrations of the other species in order to counteract the effect of this change.
For example, for the reaction:
A + B ⇌ AB
Remove A in this reaction will produce the increase in the reverse reaction in order to increase the concentration of A.
What is the rate law for this reaction? A + 2B → C + D
rate = k[A][B]2
rate = k[A]2 [B]2
rate = k[A]2 [B]
rate = k[A][B]

A 2.8 g sample of pure metal requires 10.1 J of energy to change its temperature from 21°C to 36°C. What is this metal? Substance Specific Heat Gold 0.129 J/g °C Silver 0.237 J/g °C Copper 0.385 J/g °C Water 4.18 J/g °C
Answer:
Silver 0.237 J/g °C
Explanation:
We know that the heat required to raise the temperature of a given mass of a substance through a given temperature rise is given by;
H = mcθ
Where;
m = mass of the body
c = specific heat capacity of the body
θ = temperature rise
10.1 J = 2.8 g * c * (36°C - 21°C)
c = 10.1 J / 2.8 g * (36°C - 21°C)
c = 0.24 J/g °C

Describe one piece of evidence that supports the big bang theory.
Answer: Red-Shift
Explanation:
It suggests that the universe is expanding, as distant stars/galaxies must be in motion away from us to cause the light to shift towards the red end of the spectrum (or into longer wavelengths of the EM spectrum). This agrees with the Big bang theory as that suggests the universe is expanding.
Calcular la presión final de un gas que inicialmente está a 21°C y 0,98 atm. Sabiendo que su temperatura aumenta a 37°C.
Answer:
1.03 atm
Explanation:
Primero convertimos 21 °C y 37 °C a K:
21 °C + 273.16 = 294.16 K37 °C + 273.16 = 310.16 KUna vez tenemos las temperaturas absolutas, podemos resolver este problema usando la ley de Gay-Lussac:
T₁P₂ = T₂P₁En este caso:
T₁ = 294.16 KP₂ = ?T₂ = 310.16 KP₁ = 0.98 atmColocando los datos:
294.16 K * P₂ = 310.16 K * 0.98 atmY despejando P₂:

A sample of gas is held at constant temperature. The gas is in a container with a moveable piston. The gas is
compressed into a small volume. What will happen to the pressure?
Answer:
The pressure of the gas will increase.
Explanation:
This concept of change in state properties of gas, when compressed in a moveable piston-cylinder assembly, can be explained by using Boyle's law
Boyle's law states that the pressure of a given mass of gas is inversely proportional to its volume given that temperature remains constant.
Following this law, when the gas in the container is compressed to a smaller volume, the pressure will go up.
This is also because the gas is not free to move about without frequent collisions with itself and the walls of the container, due to the resulting smaller space after compression. Therefore, the force it exerts on the walls of the container and the frequency of collision are more.

How does La Niña affect the climate of the Pacific Ocean?
1.The warm water moves toward the east.
2.The cold water sinks deeper into the ocean.
3.The ocean becomes cooler.
4.The strength of the prevailing winds decreases
The statement in which La Niña affect the climate of the Pacific Ocean is "The cold water sinks deeper into the ocean."
What is La Niña effect?La Niña is a climate phenomenon that depicts the cooling of surface ocean waters along the coast of South America's tropical west coast.
What is climateThe average weather in a certain place over a longer length of time is referred to as climate.
The jet stream moves northward and weakens across the eastern Pacific as a result of La Niña. The South experiences warmer and drier weather than usual during La Nia winters. The North and Canada are wetter and colder than the rest of the country. The seas off the Pacific coast are cooler and contain more nutrients than typical during La Niña.
Water in the eastern Pacific is colder than typical because to La Niña. El Niño might cause the water to be warmer than usual in the same place. During La Niña years, drought-stricken areas are drenched, while El Niño years are drenched.
Hence the correct option is 2.
