Answer» nfo : The INITIAL and the FINAL temperature of a copper sphere was measured by an observer to be (41.2 ± 0.1) °C and (31.0 ± 0.3) °C respectively. To find : The change in the temperature of the sphere with proper ERROR limits is ..solution : initial temperature, T₁ = (41.2 ± 0.1) °C final temperature, T₂ = (31.0 ± 0.3) °C change in temperature, ∆T = T₁ - T₂= (41.2 ± 0.1)°C - (31.0 ± 0.3)°C = [(41.2 - 31.0) ± (0.1 + 0.3) ]°C [NOTE : error must be added for any situation ] = (10.2 ± 0.4)°C Therefore change in the temperature is (10.2 ± 0.4)°C |
