When the volume of a gas is increased, the gas particles respond by spreading out and occupying a larger space. This results in a decrease in the density of the gas and a decrease in the frequency of collisions between the gas particles.
How do gas particles respond to an increase in volume?As the gas particles spread out, the pressure exerted by the gas decreases.
This is because the pressure of a gas is directly proportional to the number of collisions per unit area of the container walls. When the volume increases, the same number of gas particles are distributed over a larger area, reducing the frequency of collisions and thus decreasing the pressure.
In summary, an increase in volume causes gas particles to spread out, resulting in a decrease in density and a decrease in pressure.

Es un cambio natural o provocado, donde se produce energía para agua y dióxido de carbono: a)Precipitación. b)Fermentación c) Efervecencia. d) Combustión.
Answer:
d) Combustión.
Explanation:
¡Hola!
En este caso, dado que estamos enfocados en el concepto de cambio químico, el cual se caracteriza por exhibir un cambio en la composición e identidad de las sustancias iniciales (reactivos) a otras finales (productos).
Ahora bien, como se nos dice que los productos de este cambio químico son energía, agua y dióxido de carbono, inferimos que el nombre de este proceso es d) Combustión, por ejemplo la combustion del gas natural para calentar nuestras comidas en la cocina.

Radio waves, ultraviolet rays, X-rays, and gamma rays are all examples of electromagnetic radiation, as are microwaves.
What is Microwave?There are several uses for microwaves, including for communications, radar, and—possibly for the most part—cooking. Waves or particles of electromagnetic radiation with various wavelengths and frequencies are communicated.
The electromagnetic spectrum (EM spectrum) is the name given to this wide spread of frequencies. In general, the spectrum is divided into seven areas in ascending sequence of increasing energy and frequency and decreasing wavelength.
Radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and gamma-rays are some of the common names for these types of energy. In the electromagnetic (EM) spectrum, microwaves are found between radio and infrared light.
Therefore, Radio waves, ultraviolet rays, X-rays, and gamma rays are all examples of electromagnetic radiation, as are microwaves.

determine the number of moles and mass of the sample of argon occupying 37.8L at STP
Answer:
The number of moles and mass of the sample of argon occupying 37.8L at STP are 1.6875 moles and 67.41 grams respectively.
Explanation:
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
Then you can apply the following rule of three: if by definition of STP 22.4 L are occupied by 1 mole of Ar, 37.8 L of Ar are occupied by how many moles?
[tex]amount of moles=\frac{37.8 L* 1 mole}{22.4 L}[/tex]
amount of moles= 1.6875 moles
The atomic weight of Ar is 39.948 g/mol. So the mass of the sample of argon can be calculated as:
1.6875 moles* 39.948 [tex]\frac{g}{mol}[/tex] = 67.41 grams
The number of moles and mass of the sample of argon occupying 37.8L at STP are 1.6875 moles and 67.41 grams respectively.

The color of a star is determined by its temperature: the hottest stars are blue and the coolest are red. The Sun has a surface
temperature of 5,500°C and it appears yellow. The diagram also indicates that temperature coincides with luminosity: the hotter the
star, the higher the luminosity. You can also tell the size of each star from the graph as the larger the radius, the higher the
temperature and luminosity. Regardless of a star's position in the diagram, the energy that results in high temperatures and the stars

-cosmic rays
Answer:
Visible light
Explanation:
As mentioned in the first section of Lesson 2, our eyes are sensitive to a very narrow band of frequencies within the enormous range of frequencies of the electromagnetic spectrum. This narrow band of frequencies is referred to as the visible light spectrum. Visible light - that which is detectable by the human eye - consists of wavelengths ranging from approximately 780 nanometer (7.80 x 10-7 m) down to 390 nanometer (3.90 x 10-7 m). Specific wavelengths within the spectrum correspond to a specific color based upon how humans typically perceive light of that wavelength. The long wavelength end of the spectrum corresponds to light that is perceived by humans to be red and the short wavelength end of the spectrum corresponds to light that is perceived to be violet. Other colors within the spectrum include orange, yellow, green and blue.

How many grams of lead (II) iodide, Pbl2, is produced from 82.7 grams of potassium iodide, KI?
Round to two decimal places.
Answer:
114.8g PbI2 are produced
Explanation:
To solve this question we must convert the mass of KI to moles using its molar mass (KI = 166.0g/mol). As 2 moles of KI produce 1 mole of PbI2 we can find its moles and its mass (Molar mass PbI2: 461.01g/mol) as follows:
Moles KI:
82.7g KI * (1mol / 166.0g) = 0.498 moles KI
Moles PbI2:
0.498 moles KI * (1mol PbI2 / 2mol KI) = 0.249 moles PbI2
Mass PbI2:
0.249moles * (461.01g/mol) =

Only producers are able to capture energy from the sun and the matter from the environment to make food.How does energy that come from the sun get to every other organism?How does matter from the environment enter every other organism?
Answer:
Explanation:
Plants get energy from sunlight to produce carbohydrates. When a consumer such as herbivore consume plants, he gets energy and when a canivore or omnivore consume the primary consumer, energy is also transfered to them and this is called food chain.
Matter from the environment which include fallen leaves or trees will decompose after a while in the ground when decomposers begin to act on it and it will eventually give them energy. Decomposer help break down organic matter such as leaves,dead animals and get little amount of of energy in the energy flow pyramid
