Question

The gas in the piston is being heated, and the piston has moved upward. The observation will be summarized in a row of the incomplete table below. mc023-1.jpg Row Name Observation Variables 1 Boyle's law Volume increases when pressure decreases ? 2 Charles’s law ? ? 3 Gay-Lussac’s law ? Temperature, pressure 4 Combined gas law ? ? What are the variables for this piston?

Answer 1

The flight of a hot air balloon is attributable to Charles’s law.  

As the air in the balloon is heated, the volume of the air is increased.  

In this instance, a given weight of hot air occupies a greater volume than the same given weight of cold air, or said differently from other.
