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.
This is because a higher-than-normal temperature (a warm, balmy day) tends to be accompanied by a higher-than-normal barometric pressure of the atmosphere. That is, high temperature tends to decrease air density, while high pressure tends to increase air density. The air density ratio column in Table 3.1-1, which is the ratio of standard air density at altitude to the standard air density at sea level, shows that the air density decreases rapidly as altitude increases.
