A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

Hydraulic power. Hydraulic power, also called Fluid Power, power transmitted by the controlled circulation of pressurized fluid, usually a water-soluble oil or waterâglycol mixture, to a motor that converts it into a mechanical output capable of doing work on a load.
nominal power An estimate of the power of a lens, calculated as the sum of the front and back surface powers, i.e. Syn. approximate power. See equivalent power; surface power. prism power The amount of deviation of a ray of light transmitted through a prism or lens (outside its optical centre).
