Continuing with chemistry and physics, this week is states of matter.
気体 – ããŸã„ – gas
液体 – ãˆããŸã„ – liquid
固体 – ã“ãŸã„ – solid
Be careful to differentiate “solid†from the similar word:
個体 – ã“ãŸã„ – individual
相 – ãㆠ– phase
気相 – vapor phase
液相 – liquid phase
固相 – solid phase
相転移 – ãã†ã¦ã‚“ã„ – phase transition
èžç‚¹ – ゆã†ã¦ã‚“ – melting point
沸点 – ãµã£ã¦ã‚“ – boiling point
臨界点 – りんã‹ã„ã¦ã‚“ – critical point
Example sentences:
æ°´ã¯æ¶²ä½“ã§ã‚る。- ã¿ãšã¯ãˆããŸã„ã§ã‚る。- Water is a liquid.
ãƒã‚ªãƒ³ã¯æ°—体ã§ã‚る。- ããŠã‚“ã¯ããŸã„ã§ã‚る。 – Neon is a gas.
鉄ã¯å›ºä½“ã§ã‚る。- ã¦ã¤ã¯ã“ãŸã„ã§ã‚る。- Iron is a solid.

Since I spent a month going over the periodic table, I thought this would be a good time to go over some vocabulary related to the elements and the periodic table.
First, some basics:
å…ƒç´ – ã’ã‚“ã element
å…ƒç´ è¨˜å· – ã’ã‚“ããã”ㆠ– chemical symbol
原åç•ªå· – ã’ã‚“ã—ã°ã‚“ã”ㆠ– atomic number
周期表 – ã—ã‚…ã†ãã²ã‚‡ã† – periodic table
ã’ã‚“ãã®ã—ã‚…ã†ãã²ã‚‡ã† – ã’ã‚“ãã®ã—ã‚…ã†ãã²ã‚‡ã† – periodic table of the elements
Now, some of the elemental groups:
アルカリ金属 – ã‚ã‚‹ã‹ã‚Šãã‚“ãžã – alkaline metal
アルカリ土類金属 – ã‚ã‚‹ã‹ã‚Šã©ã‚‹ã„ãã‚“ãžã – alkaline earth metal

I thought it would be interesting to see what some of the different types of numbers are in Japanese.
実数 – ã˜ã£ã™ã† – real number
æœ‰ç†æ•° – ゆã†ã‚Šã™ã† – rational number
ç„¡ç†æ•° – むりã™ã† – irrational number
虚数 – ãょã™ã† – imaginary number
è¤‡ç´ æ•° – ãµããã™ã† – complex number
åˆ†è§£åž‹è¤‡ç´ æ•° – ã¶ã‚“ã‹ã„ãŒãŸãµããã™ã† – split-complex number
二元数 – ã«ã’ã‚“ã™ã† – dual number
二元数 can also refer, in a broad sense, to complex and split complex numbers as well.
四元数 – ã—ã’ã‚“ã™ã† – quaternian
八元数 – ã¯ã¡ã’ã‚“ã™ã† – octonian
I think the japanese words for the higher dimensional numbers are particularly interesting. Somehow the more direct representations seem like they would be easier to understand than the latin prefixes.
