Respuesta :
Pushing down on the piston causes an increase in pressure and a decrease in the volume of the gas in the cylinder. This is BEST explained by the fact that the pressure is always inversely proportional with volume at constant temperature and number of moles of substance.
Answer: The answer is D on usa test prep
Explanation:The decrease in volume as a result in an increase in pressure is BEST explained by the fact that there is a large relative distance between gas molecules. This explains the property of compressibility, exhibited by gases under pressure.
