$(37.7 \pm 0.5)^{\circ} C$

Vedclass · Answer

$	heta_1=(40.6 \pm 0.2)^{\circ} C , 	heta_2=(78.3 \pm 0.3)^{\circ} C$

Rise in temperature, $	heta=	heta_2-	heta_1=78.3-40.6=37.7^{\circ} C \Delta 	heta$

$= \pm\left(\Delta 	heta+\Delta 	heta_2ight)$

$=\pm(0.2+0.3)=0.5^{\circ} C$

Hence, rise in temperature $=(37.7 \pm 0.5)^{\circ} C$

The initial and final temperatures of water as recorded by an observer are $(40.6 \pm 0.2)^{\circ} C$ and $(78.9 \pm 0.3)^{\circ} C .$ Calculate the rise in temperature with proper error limits.
