The natural gas is composed of methane, butane, propane and a small amount of iso-Butane.
These all are organic compound (alkanes) and burn in presence of the oxygen to give carbon dioxide. The burning of the alkanes is type of exothermic reaction, which means they liberate heat energy on reaction. The enrgy is released due to the braking of the bond and the formation of the new bonds.
Hence, it can be concluded the chemical taking place at the time of burning of these gases gives off the energy.

Answer:
into the cell from the solution causing it to expand
Explanation:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Diagram of red blood cells in hypertonic solution (shriveled), isotonic solution (normal), and hypotonic solution (puffed up and bursting).
