WebbTo find uncertainties in different situations: The uncertainty in a reading: ± half the smallest division. The uncertainty in a measurement: at least ±1 smallest division. The uncertainty in repeated data: half the range i.e. ± ½ (largest - smallest value) The uncertainty in digital readings: ± the last significant digit unless otherwise ... WebbThermodynamics is the study of heat. A thermos either keeps heat in or out. You wear thermal underwear to prevent body heat from escaping. Despite its name, however, a thermometer does not actually record heat, but rather temperature. Temperature and heat are two radically different concepts.
