WebIf we heat something up or cool it, the length changes in proportion to the original length and the temperature change. ΔL = α × L × ΔT. with: ΔL being the variation in object length (in, m) α being the linear expansion coefficient (1/°F, 1/°C) L being the object's original length (in, m) ΔT being the temperature change (°F, °C). WebCalorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter). The temperature …
