If an enclosed gas container with moveable piston is heated. What will happen?

اگر حرکت پذیر پسٹن کے ساتھ بند گیس کنٹینر کو گرم کیا جاتا ہے۔ کیا ہو گا؟
Explanation
Heating a gas in a container with a movable piston increases the kinetic energy of gas molecules.
This causes the gas to expand, pushing the piston outward and increasing the volume.
