<prompt> Coefficient ea katoloso ea mocheso ke eng?Ha ho hlokahale tlhahiso  <response>: Instruction in English: What is the coefficient of thermal expansion? . Response in English: The coefficient of thermal expansion α is a measure of the change in size of a material with a change in temperature. It is defined as the fractional change in length or volume per unit change in temperature. The value of the coefficient of thermal expansion depends on the material being considered and can be expressed in units of inverse degrees e.g. 1C or 1F. Different materials have different coefficients of thermal expansion. For example metals generally have a relatively high coefficient of thermal expansion whereas ceramics have low coefficients. The coefficient of thermal expansion is an important consideration in applications where a change in temperature can result in changes in size that can cause problems in the design or operation of a system. . Response in Sesotho: Coefficient ea ho atolosa mocheso α ke tekanyo ea phetoho ea boholo ba thepa e nang le phetoho ea mocheso. E hlalosoa e le phetoho e fokolang ka bolelele kapa molumo ka unit e fetoha mocheso. Boleng ba coefficient ea katoloso ea mocheso bo itšetlehile ka thepa e nahanoang me e ka hlalosoa ka likarolo tsa likhato tse fapaneng mohlala, 1C kapa 1F. Lisebelisoa tse fapaneng li na le li-coefficients tse fapaneng tsa katoloso ea mocheso. Ka mohlala, litšepe ka kakaretso li na le coefficient e batlang e phahame ea katoloso ea mocheso athe li-ceramic li na le li-coefficient tse tlase. Coefficient ea ho atolosoa ha mocheso ke ntho ea bohlokoa ho nahanela litsebetsong moo phetoho ea mocheso e ka fellang ka liphetoho tsa boholo bo ka bakang mathata ho moralo kapa tsebetsong ea tsamaiso.
