The temperature and pressure rise.
must decrease
The density will decrease
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
The mass should not change but will decreases slightly due to evaporation. The volume will decrease.
The density becomes lower: Density is defined as mass/volume, and if mass decreases while volume remains the same, the quotient must decrease.
If volume increases while mass remains the same, the density will decrease.
Density = Mass / Volume Therefore: Increase in Mass --> Increase in Density Increase in Volume --> Decrease in Density and Vice Versa.. :) Hope this helped
Density is a characteristic of a given material. Water, for example, has a certain density (which is somewhat dependent upon temperature but let's say that the temperature is constant). It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
If the volume remains the same, the density will increase in direct proportion to the increase in mass.
it decreases.
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
