Answer 2

Answer:

Explanation:

The element gallium is an unexpected metal—it's a soft, silvery-white metal that is solid at room temperature (similar to aluminum) but it can literally melt in the palm of your hand. It's bizarre and a little unsettling to see, but it makes sense. The melting point for gallium (which is represented on the Periodic Table as Ga) is relatively low, at 85.6°F (29.8°C). However, the boiling point for this element is quite high, at 4044°F (2229°C). This quality makes gallium ideal for recording temperatures that would destroy a thermometer. According to the Los Alamos National Laboratory, gallium is "one of four metals — mercury, cesium, and rubidium — which can be liquid near room temperature and, thus, can be used in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapor pressure even at high temperatures."
