If the Earth were to be moved to where Venus is today,
A) the oceans would evaporate, blocking light from the Sun and causing global temperatures to fall
B) carbon dioxide would be released from the oceans leading to higher temperatures but liquid water could still exist on the surface
C) the oceans would evaporate slightly producing a slightly warmer, more humid planet
D) the oceans would evaporate and carbonate rocks would decompose producing a runaway greenhouse effect much more severe than the one that exists on Venus today

An opaque horizontal plate is insulated on the backside. The plate irradiation is 2500 W/m^2 of which 500 W/m^2 is reflected. The plate temperature is 227ºC and has an emissive power of 1200 W/m^2. Air at 127ºC and with a convective heat transfer coefficient of 12 W/m^2 K flows over the plate. Determine (a) emissivity, absorptivity, and radiosity of the plate and (b) the net heat transfer per unit area.

A key step in the destruction of ozone by chlorofluorocarbons is
