Metal Gallium is a liquid at room temperature. It's melting point is 29.76°C. The freezing point of water is 0°C. How much warmer is the melting point of Gallium than the freezing point of water?
Answers
Step-by-step explanation:
metal Gallium is a liquid at the room temperature.
it's melting point is 29.76.
the freezing point of water is 0C
How much warmer is the melting point of Gallium than the freezing point of water?
= 29.76is warmer than the water
Answer:
Elemental gallium is a soft, silvery blue metal at standard temperature and pressure, a brittle solid at low temperatures, and a liquid at temperatures greater than 29.76 °C (85.57 °F) (slightly above room temperature). The melting point of gallium is used as a temperature reference point. The alloy galinstan (68.5% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19 °C (−2 °F), well below the freezing point of water.
Step-by-step explanation:
- At normal temperature and pressure, the elemental gallium is a soft, silvery metal; but, when it becomes liquid, it turns silvery white.
- Given that it belongs to group 13 of the periodic table, it has characteristics with the other metals in the group, including thallium, indium, and aluminium.
- In nature, gallium does not occur as a free element, but rather in minuscule quantities as gallium(3) compounds in zinc ores and bauxite.
- Elemental gallium melts in a person's hands at a temperature of 37 °C (99 °F), which is the average body temperature. Elemental gallium is a liquid at temperatures higher than 29.76 °C (85.57 °F). The temperature reference point is gallium's melting point.
- Gallium has a melting point of 302.9146 K, which is barely over room temperature and almost equal to the normal summer midday temperatures in Earth's mid-latitudes (29.7646 °C, 85.5763 °F). The International Bureau of Weights and Measures' International Temperature Scale of 1990 (ITS-90) includes this melting point (MP) as one of its official temperature reference points (BIPM). Gallium's triple point is 302.9166 K (29.7666 °C; 85.5799 °F).
