The only option that would increase the pressure of a gas in a container is B. Increasing the temperature of the gas. Option B
To understand which factor would increase the pressure of a gas in a container, we need to consider the relationship between pressure and various variables in the ideal gas law and the kinetic theory of gases.
The ideal gas law states that pressure (P) is directly proportional to the number of gas particles (n), the temperature (T), and inversely proportional to the volume (V) of the container. Mathematically, it can be expressed as:
PV = nRT
where R is the ideal gas constant.
Based on this equation, we can analyze the options given:
A. Decreasing the kinetic energy of the gas: According to the ideal gas law, temperature is directly proportional to pressure. Therefore, decreasing the kinetic energy (which is related to temperature) would decrease the pressure, not increase it.
B. Increasing the temperature of the gas: As mentioned above, temperature is directly proportional to pressure. Increasing the temperature of the gas would increase its kinetic energy, resulting in more frequent and energetic collisions with the container walls, thus increasing the pressure.
C. Decreasing the number of gas particles: According to the ideal gas law, the number of gas particles (n) is directly proportional to pressure. Therefore, decreasing the number of gas particles would decrease the pressure, not increase it.
D. Increasing the volume of the container: According to the ideal gas law, volume (V) is inversely proportional to pressure. Increasing the volume of the container would decrease the pressure, not increase it.

The volume of a gas was 48 mL when the temperature was 159.6 ºC. If the temperature was initially 4.9 ºC, and there was no change in the pressure, what was the initial volume of the gas?
According to Charles law

A fixed mass of gas has a volume of 92 cm cube and 3 degrees Celsius. What will be its volume at 18 degrees celsius if the pressure remains constant?
Answer:
94.8454
Explanation:
Let volume be V
Let Temperature be T
V1= 92
T1= 3C but to kelvin 273+3= 300K
V2= ?
T2= 18 C but to kelvin 18+273= 291
[tex] \frac{v1}{t1} = \frac{v2}{t2} [/tex]
[tex] \frac{92}{300} = \frac{v2}{291} [/tex]

Explain how the existence of ions relates to the number of electrons present in atoms of an element? (A.P.E.X)
Answer:
if you have options please include them, but I'll give you an idea.
Explanation:
The existence of ions happens when atoms lose or gain electrons.
if an atom gains an electron it will become a negative ion (because electrons are negative, and you gained more negativity.)
if an atom loses an electron it will become a positive ion (because it has lost negativity, which is the electron that we've lost).

What is the pressure of 4 moles of helium in a 50 L tank at 308 K?
Use PV = nRT.
A. 24.64 atm
B. 0.13 atm
O C. 0.51 atm
D. 2.02 atm
Answer:
D
Explanation:
P = Pressure
V = Volume
n = Moles
R = .08206 (because we're using liters)
T = Temperature (as K)
P(50) = (4)(.08206)(308)
P(50) = 101.09792
Divide both sides by 50
P(50)/50 = 101.09792/50
P = 2.0219584
Answer:
[tex]\boxed {\boxed {\sf D. \ 2.02 \ atm}}[/tex]
Explanation:
We are asked to find the pressure of helium gas using the ideal gas law.
[tex]PV= nRT[/tex]
In this formula P is the pressure, V is the volume, n is the number of moles of gas, R is the universal gas constant, and T is the temperature.
The pressure is unknown and we are solving for it. The volume is 50 liters, there are 4 moles of helium gas, the universal gas constant is 0.08206 L *atm/ mol * K, and the temperature is 308 Kelvin.
[tex]\bullet \ V= 50 \ L \\\bullet \ n= 4 \ mol \\\bullet \ R = \frac {0.08206 \ L * atm}{mol *K}\\\bullet \ T= 308 \ K[/tex]
Substitute these values into the formula.
[tex]P * 50 \ L= 4 \ mol * \frac {0.08206 \ L * atm}{mol *K} * 308 \ K[/tex]
Multiply on the right side. The units of moles (mol) and Kelvin (K) cancel each other out.
[tex]P* 50 \ L = 4 * 0.08206 \ L *atm * 308[/tex]
[tex]P*50 \ L =0.32824 \ L * atm *308[/tex]
[tex]P* 50 \ L = 101.09792 \ L * atm[/tex]
We are solving for the pressure, so we must isolate the variable P. It is being multiplied by 50 liters. The inverse operation of multiplication is division, so divide both sides by 50 L.
[tex]\frac {P* 50 \ L}{50 \ L} = \frac {101.09792 \ L * atm}{50 \ L}[/tex]
[tex]P= \frac {101.09792 \ L * atm}{50 \ L}[/tex]
The units of liters (L) cancel.
[tex]P= \frac{101.09792}{50 } \ atm[/tex]
[tex]P= 2.0219584 \ atm[/tex]
If we round to the nearest hundredth place the 1 in the thousandth place tells us to leave the 2 in the hundredth place.
[tex]P \approx 2.02 \ atm[/tex]
The pressure is approximately 2.02 atmospheres and choice D is correct.

Define physical and chemical properties, provide three examples of each, discuss their reversibility, and explain the fundamental differences between them.
Answer:
Physical properties are defined as the properties which can be observed without changing their chemical composition.
For example, color, volume, and molecular weight.
Chemical properties can be defined as, a properties that can be seen only after changing the substance's chemical identity.
For example, reactivity, toxicity, and flammability.
The fundamental differences between physical and chemical properties are as follows:
Chemical properties are related to chemical bonds of the substance, while physical properties are not.
In chemical properties, the chemical identity of substance changes while physical properties does not have any change.
Chemical properties predict the reaction of a substance, while physical properties only describe the appearance of the substance.
