Answer:
plese dont mind
Explanation:
explained the question
Answer:
4. yes ex- water
5. the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
6.Cool roofs are typically painted white because lighter surfaces reflect more light than darker ones. This lowers the air and surface temperature and less heat energy finds its way into the building.
7. Wien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature.
8.the average distance travelled by a gas molecule or other particle between collisions with other particles.
