Because Venus has a very thick, dense atmosphere, rich in CO2, which retains heat - you could call it a runaway Greenhouse effect. Mercury, on the other hand, has only a very thin, almost negligible atmosphere, allowing heat to escape quicker (and drop very low on the 'night-time' side of the planet).

there is a high concentration of carbon dioxide in the atmosphere of Venus.
this causes a greenhouse effect which traps the heat inside the atmosphre.
because of this the temperature of venus is higher than mercury

When sunlight enters Venus, the atmostphere traps the sun's heat but allowing light to get out. Thus, the planet is heated up to an amazing 430 degrees.

Not all the heat warming a planet comes from the sun.
Inside the core of the planet heat is generated by radioactive decay.
This obviously depends on the amount of radiactive material within the planet.

The same greenhouse effect that scientists think is threatening Earth today. Once there are a certain amount of greenhouse gases in the atmosphere, the process can sustain itself. You can imagine the consequences.

its atmosphere has much higher concentration of Carbon dioxide that traps the sun's heat (greenhouse effect) raising the surface temperature to one greater than that on mercury.

It has a massive greenhouse effect

Because the Venusians didn't believe in global warming either!
