# The initial and final temperature of a liquid in a container are observe to be $76.3 \pm0.5 ^{\circ} c$ and $27.7 \pm 0.2 ^{\circ} c$. Find the fall in temperature.

$(a)\;48.6 \pm 0.3 ^{\circ}c$$(b)\;46.8 \pm 0.7 ^{\circ}c$$(c)\;48.6 \pm 0.7 ^{\circ}c$ $(d)\;46.8 \pm 0.3 ^{\circ}c$

Can you answer this question?

Fall in temperature $= (76.3 \pm 0.5^{\circ}c)-(27.7 \pm 0.2^{\circ}c)$
$=48.6 \pm 0.7 ^{\circ}c$
Hence c is the correct answer.
