Question:

A thermometer is taken from a room where the temperature is {eq}20^\circ C {/eq} to the outdoors, where the temperature is {eq}5^\circ C {/eq}. After one minute the thermometer reads {eq}12^\circ C {/eq}. (Round the answers to one decimal place.)

(a) What will the reading on the thermometer be after one more minute?

(b) When will the thermometer reads {eq}6^\circ C {/eq} ?

Let,

{eq}T_0=\text{ higher temperature }=20^\circ C\\ T_s=\text{lower temperature }=5^\circ C\\ {/eq}

And therefore,

{eq}\dfrac{\mathrm{d}...
