Answer:
The pressure inside the container will increase by increasing the amount of gas.
Step-by-step explanation:
It can be better understand through ideal gas equation,
PV = nRT
By keeping the volume and temperature constant, the pressure of gas in container will increase when amount of gas goes to increase.
PV = nRT
P = nRT / V
P = (1+ 14) RT/V
P = 15
The pressure will increase 15 fold.
