Juana is creating a lab simulation about the movement of the particles in a nonmetal gas. The user can change the pressure in the gas' temperature and see the effect of the change in the gas' volume. What changes should Juana program to cause the decrease in the gas' volume?

Increase gas pressure and decrease gas temperature

Explanation:

To Create a lab simulation whereby the changes in pressure exerted on the gas will affect the volume of the gas volume negatively ( decrease in gas volume ) the changes that Juana should program is to increase the pressure on the gas molecules because increase in gas pressure  = decrease in gas volume while increase in temperature will lead to increase in gas

Hence in order to effectively achieve the decrease in gas volume with the lab simulation; she should increase gas pressure and decrease gas temperature
