The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be expected to change?
1. It would remain constant.
2. It would increase.
3. It would become zero.
4. It would decrease.
The correct answer is: 2. It would increase.
When the volume is held constant and the temperature of an ideal gas increases, according to the ideal gas law (PV = nRT), the pressure (P) would increase.
So, the correct answer is: 2. It would increase.
To determine how the pressure would change when volume is held constant and the temperature increases, we can refer to the ideal gas law equation PV=nRT.
In this scenario, we are keeping the volume constant (V is constant) while increasing the temperature (T increases).
Since the amount of gas (n) and the gas constant (R) are also constant, we can simplify the equation to PV = constant.
According to Boyle's law, when the volume of a gas is held constant, there is an inverse relationship between pressure and temperature. This means that as the temperature increases, the pressure decreases.
Therefore, the correct answer is:
4. It would decrease.
