Answer 1

Explanation:

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet's temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter

Answer 2

Mercury doesn't have any atmosphere, and atmosphere can hold and trap heat.The atmosphere of venus is very hot and thick so, the heat remains trapped inside it.

Mercury is 426 degrees hot and venus is 471 degrees hot.
