Using the formula density = mass / volume, explain what will be the effect of heat on the gas kept in a closed bottle.

Answer»

density will decrease.Explanation: we know the ideal gas EQUATION that pv=nrt where p is the pressure, v is the volume n is no. of moles R is gas constant and t is temperature from this equation we can conclude:pv=nrttherfore volume is directly proportion to TEMPERATUREON increasing HEAT volume increases.   (1) now, density = mass/volume density is INVERSELY proportional to volume.on incresing volume density decrease  (2)from (1) we have increased volume therfore by (2) density decrease
