What would venus's "no greenhouse" temperature be if its clouds were more transparent, giving a reflectivity similar to earth's? (b) what would the actual surface temperature now be if the greenhouse effect increased its temperature by the same number of degrees it does today?

1.

2.539C

Explanation:

Green house gases is known as the gases that educes the infrared radiation of the earth crust. If allows ultraviolet rays of the sun penetrate into the ozone layer(a protective covering in the earth's atmosphere.

Venus is known as the earth's twin because of it close proximity in size with the earth.

venus "no greenhouse" temperature will be if its clouds were more transparent, giving a reflectivity similar to earth.

2, The actual surface temperature will be  539 deg C, if the green house effect increased . green house effect will actually increase the surface temperature of the venus.
