Question

In the simulation, adjust the temperature and observe how the pressure of the gas changes. What happens to the pressure of the gas when the temperature is increased at constant volume?


The pressure stays the same.


The pressure decreases.


The pressure increases.


The gas condenses.

Answer 1

According to the ideal gas law, which is expressed as \( PV = nRT \) (where \( P \) is pressure, \( V \) is volume, \( n \) is the number of moles of gas, \( R \) is the gas constant, and \( T \) is temperature), if you increase the temperature (\( T \)) while keeping the volume (\( V \)) constant, the pressure (\( P \)) of the gas will increase.

Therefore, the correct answer is:

**The pressure increases.**
