The reason why they gain weight over time is because of the food(s) they eat.
pennies will grow dirt and things on them over time, but no. a dirtier penny will always weigh more and be a little bigger than a brand new one.
two weeks is not enough time to gain any signifigant muscle mass
For a time you will gain weight because muscle weighs more. Over time, your body shape and weight will change. Keep on with the program.
yes
Energy is converted to mass every time your car takes you across town. As the car accelerates from its relative speed of zero, it gains mass because is gains kinetic energy (and gives up mass as it slows and loses kinetic energy). The amount of gain is so tiny at driving speeds as to be unmeasurable, but there is a gain in mass any time any mass is accelerated. At speeds approaching the speed of light, the mass gain is much more appreciable. You can calculate the amount of gain by manipulating the equation E=mc2: m=E/c2. Since c2 in the denominator is such an enormous number, you can see that the amount of mass gained for relatively small increases in kinetic energies will be very tiny.
Give it special food and walk it every day over time it will gain so gl
No. The sun is decreasing in mass (fusion) over time whereas a black hole would increase in mass over time (sucking up astroids, gas, etc). So over very long periods of time the sun's gravitational force will significantly decrease, and if it was a black hole it would increase. Increase/decrease in mass directly affects increase/decrease in gravitational force. Since gravitation (and motion) is what causes orbit, over long periods of times the planets would have very different orbits in the two scenarios (sun vs black hole).
i was 95lbs 4 months ago im now 104 what you want to do is start hitting the weights and use MHP's Up Yor Mass and dude you will be on a tear and gain mass in no time
It really depends on your interest rate. Usually your investment company will give you a booklet showing how much would you gain after certain time.

Yes. And if massive enough then the density may increase due to gravitational attraction in a matter of time we can perceive. even with a small mass this is happening, however it may take 1000s to millions of years for it to be measurable.In most cases the mass would remain the same (absent radioactivity losses) but the density would increase. If highly radioactive its mass would likely decrease over time.
Mass and energy are equivalent, so there are exchanges of between mass and energy any time there is a change in motion (kinetic energy). But Atomic energy is the most familiar conversion of mass into energy. The explosion of an nuclear bomb, or the energy generated by a nuclear reactor are consequences of conversion of mass into energy. Energy from combustion is not primarily derived from mass/energy conversion, but from exothermic chemical reactions. In fact, any such exchange between mass and energy would operate in the other direction, as gasses gain mass as they are put into motion (increased kinetic energy=increased mass). But any such gain is so tiny as to be meaningless.
