Mercury was chosen for use in diffusion pumps primarily due to its high vapor pressure at relatively low temperatures, which allows for efficient pumping of gases. Its liquid state at room temperature enables effective sealing and minimal gas leakage. Additionally, mercury's high Atomic Mass contributes to its ability to effectively remove lighter gases from the vacuum chamber, enhancing the overall pumping efficiency. However, safety concerns related to mercury's toxicity have led to the development of alternative materials in modern applications.

How do you get to mercury?

To get to Mercury, you would need a spacecraft launched from Earth. Due to its proximity to the Sun and the high speeds required to reach it, spacecraft usually perform multiple gravity-assist maneuvers around other planets before arriving at Mercury. The journey can take several months to a few years depending on the trajectory chosen.

Through passive transport


What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?

When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
