its volume is doubled
Which of the following are the properties of gas used in calculating Boyle’s Law?
pressure and temperature
volume and pressure
Which of the following situations shows Charles’ Law?
As you inhale, the lung cavity expands, causing the pressure inside the lungs to decrease and become lower than the outside pressure
Sky lanterns rise as the temperature increases and the density of the gas decreases as gas expands at the bottom of the aquarium is higher than the pressure near the surface
