A mountain climber finds that water boils at 80° C. The temperature of this boiling water is…… Fahrenheit
\(\frac{F-32}{9}=\frac{80}{5}\)
F –32 = 144 or F = 176 º F.
The temperature of an iron block is 140º F. Its temperature on the Celsius scale is
\(\frac{140-32}{9}=\frac{C}{5}\: or\: \frac{700-160}{9}=C\: or\: C=60^{\circ}C\)
According to Newton’s law of cooling, the rate of cooling of a body is proportional to (Δθ)n, where Δθ is the difference of the temperature of the body and the surroundings, and n is equal to
