<prompt> Hlalosa hore na ke hobaneng ha metsi a atoloha ha a hoama.nan  <response>: Instruction in English: Explain why water expands when it freezes. . Response in English: Water expands when it freezes into ice because of the unique structure of its molecules. Water is made up of two hydrogen atoms and one oxygen atom, forming a bent or V shape. As water cools down, the water molecules start to slow down and form a more structured, crystalline lattice. This structure, which is called the hexagonal structure- occurs due to waters hydrogen bonds.Hydrogen bonds occur between the hydrogen atoms of one water molecule and the oxygen atoms of another water molecule. These hydrogen bonds cause water molecules to push apart as they arrange themselves into this crystalline lattice structureand hence occupy more space. Ice takes more space than liquid water, like gaps created between the molecules in this lattice structure, which make ice less dense than liquid water. In scientific terms, the decrease of density leads an increase in volume, resulting in the expansion of water when it freezes.This property of expanding when frozen is quite rare and makes water unique as most liquids become denser when they turn into a solid state. This is also the reason why ice floats on top of liquid water. . Response in Sesotho: Metsi aa ata ha a hoama ho ba leqhoa ka lebaka la sebōpeho se ikhethang sa limolekhule tsa ona. Metsi a entsoe ka liathomo tse peli tsa hydrogen le athomo e le ngoe ea oksijene, a etsa sebopeho se kobehileng kapa V. Ha metsi a ntse a pholile, limolekhule tsa metsi li qala ho fokotseha me li etsa lesela le hlophisitsoeng haholoanyane, la kristale. Sebopeho sena, se bitsoang hexagonal structure - se etsahala ka lebaka la likamano tsa hydrogen tsa metsi. Litlamo tsa haedrojene li etsahala pakeng tsa liathomo tsa hydrogen tsa molekhule e le ngoe ea metsi le liathomo tsa oksijene tsa molekhule e ngoe ea metsi. Litlamo tsena tsa haedrojene li etsa hore limolekhule tsa metsi li arohane ha li ntse li itlhophisa ka hara sebopeho sena sa kristale-me ka hona li nka sebaka se eketsehileng. Leqhoa le nka sebaka se seholo ho feta metsi a mokelikeli, joalo ka likheo tse entsoeng pakeng tsa limolekhule tse ka hara sebopeho sena sa lethapo, tse etsang hore leqhoa le se teteane ho feta metsi a metsi. Ho ea ka saense, ho fokotseha ha sekhahla ho lebisa ho eketseha ha molumo, ho fella ka ho atoloha ha metsi ha a hoama. Thepa ena ea ho hola ha e hoamme ha e fumanehe haholo me e etsa hore metsi a be a ikhethang kaha lino tse ngata li teteana ha li fetoha boemo bo tiileng. Hape ke lona lebaka leo leqhoa le phaphametseng holima metsi a mokelikeli.
