Question

you are a research chemist. an experiment requires incubation in a 37 °c, temperature - controlled water bath. the water bath is currently at 20 °c. you know that it takes 3 minutes to raise the temperature by 1 °c. how many minutes will it take to heat up the water bath to the required temperature?
a. 2
b. 6
c. 17
d. 19
e. 51

Explanation:

Step1: Calculate temperature difference

$37 - 20=17^{\circ}C$

Step2: Calculate heating - time

Since it takes 3 minutes to raise the temperature by $1^{\circ}C$, the time $t$ is $t = 17\times3=51$ minutes

Answer:

E. 51
