Question
P*V = n*R*T
where
P = pressure
V = volume
n = number of moles
R = the universal gas constant
T = temperature in degrees Kelvin
This equation is known as the ideal gas law, and it can be used to predict the behavior of many gases at relatively low pressure.
From this equation, you can see that as the temperature of a gas increases,
Responses
A the pressure of the gas increases.the pressure of the gas increases.
B the number of moles of gas will go down.the number of moles of gas will go down.
C either the pressure of the gas, the volume of the gas, or both, will increase.either the pressure of the gas, the volume of the gas, or both, will increase.
D either the pressure of the gas, the volume of the gas, or both, will decrease.
C either the pressure of the gas, the volume of the gas, or both, will increase.
From the ideal gas law equation, P*V = n*R*T, when the temperature of a gas increases, the correct response is:
C - either the pressure of the gas, the volume of the gas, or both, will increase.
To determine the answer to this question, we need to look at the ideal gas law equation, P*V = n*R*T, and analyze the relationship between temperature (T) and the variables: pressure (P), volume (V), and number of moles (n).
According to the ideal gas law equation, when the temperature increases, the other variables must also change in order to maintain equilibrium. Let's examine the possible options:
A) The pressure of the gas increases.
According to the ideal gas law equation (P*V = n*R*T), if the temperature (T) increases, and we want to preserve the product on the left side of the equation, then the pressure (P) must also increase. So, A is a valid response.
B) The number of moles of gas will go down.
The number of moles (n) is not directly related to the temperature (T) in the ideal gas law equation. It primarily depends on the amount of substance present, which is an intrinsic property of the gas. Therefore, B is not a correct response.
C) Either the pressure of the gas, the volume of the gas, or both, will increase.
This statement is partially correct. As mentioned earlier, if the temperature (T) increases, the pressure (P) must also increase to maintain equilibrium. However, the volume (V) can either increase or stay the same, depending on the conditions. So, C is a valid response.
D) Either the pressure of the gas, the volume of the gas, or both, will decrease.
This statement is incorrect. If the temperature (T) increases, the pressure (P) must increase to maintain equilibrium. The volume (V) can decrease, increase, or remain the same, depending on the conditions. Therefore, D is not a correct response.
In summary, the correct answer is:
A) the pressure of the gas increases.
