The apparatus consists of a bimetal strip mounted within an insulating plastic handle. When the metal strip is heated, the unequal expansion of the two metals causes the bar to bend, illustrating how thermostats respond to temperature changes. This simple and effective model helps students understand heat transfer and material properties through direct observation. Suitable for repeated classroom demonstrations, the compound bar supports lessons on properties of matter and thermal behavior. Product dimensions are approximately 0.7 inches long x 0.7 inches wide x 9.75 inches high. Instructions are included.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Features\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"3018\" data-end=\"3072\"\u003eDemonstrates thermal expansion using a bimetal strip\u003c\/li\u003e\n\u003cli data-start=\"3075\" data-end=\"3131\"\u003eVisual bending action illustrates thermostat operation\u003c\/li\u003e\n\u003cli data-start=\"3134\" data-end=\"3184\"\u003eInsulating plastic handle supports safe handling\u003c\/li\u003e\n\u003cli data-start=\"3187\" data-end=\"3241\"\u003eCompact design suitable for classroom demonstrations\u003c\/li\u003e\n\u003cli data-start=\"3244\" data-end=\"3294\"\u003eIncludes instructions for guided educational use\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GSC International Inc.","offers":[{"title":"Default Title","offer_id":46229144404107,"sku":"GS-4-30901","price":22.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0339\/3863\/6939\/files\/4-30901CompoundBar-Photoroom.jpg?v=1773843266","url":"https:\/\/uberbazaar.com\/products\/compound-bar-metal-plastic-9-75-h-physics-classroom-demonstration-tool-by-gsc-international","provider":"Uber Bazaar","version":"1.0","type":"link"}
