Just like dimples in the face, some people are born with back dimples no matter their body fat percentage. Remember! Despite of all the sweating diet control and hard work, if you don't have it in your genes, the probability of you NOT getting back dimples are high as they are genetic makeup. This disappointing but it is a fact.
When the volume is increased while the mass remains, the density increases. One way to increase volume is by reducing the temperature of objects especially gases. This is how â¦ air conditioning and fridges work, cooling the air which will move down as denser objects sink.
A few examples include: Plate Tectonics â Density is a factor for â¦ Mantle Convection Behavior of Pollutants Density of Pollutants Affects Flow Sediments Flowing into the Ocean Factors Affecting Density Temperature As the temperature of most substances increases Atoms move faster and spread apart. Expansion increases the volume which decreases the density because the mass remains the same. Pressure Solids At great depths below Earthâs surface there is extremely high pressure from the overlying rocks. Minerals are compressed Volume decreases. Density increases Fluids (Particularly gases such as the atmosphere) As pressure decreases, gases expand. This results in an increase in volume. Density decreases Shape and Size If the temperature of a material remains constant, the size and shape will not affect itâs density. The mass and volume change proportionately. Phases of Matter For most substances particles are most closely packed in the solid phase.
