Discuss the evidence that suggests that Venus is still very active volcanically
What will be an ideal response?
There are hundreds of volcanoes on the surface of Venus. Atmospheric chemistry has shown levels of sulfur dioxide that show large and frequent fluctuations, which could be produced by active volcanism. Bursts of radio radiation similar to those from volcanic eruptions on Earth have also been observed. Venus Express has also mapped areas that are warmer, indicative of volcanism in the comparatively recent past.

Consider the cooling of (a) a personal computer with a separate CPU, and (b) a laptop computer. The reliable functioning of these machines depends upon their effective cooling. Identify and briefly explain all modes of heat transfer that are involved in the cooling process.
GIVEN - A personal computer with a separate CPU (the monitor, keyboard, and mouse are separate and not considered). - A laptop computer. FIND Identify and describe modes of heat transfer involved in their cooling. ASSUMPTIONS - The computers are turned on and in normal operation.
