The three steps of a chemistry lab experiment are listed here. The experiment begins with a compound that is stored at -40oF.
Step 1 Raise the temperature of the compound 200o.
Step 2 Add sulfur and then raise the temperature 10o.
Step 3 Add 10 mililiters of water, stir, and raise the temperature 25o.
What is the resulting temperature of the mixture after step 3?
Answer = (1) oF
Correct Answer
(1) 195
Explanation
The compound starts at −40°F
Step 1
Raise temperature by 200°
\[-40 + 200 = 160^\circ F\]
Step 2
Raise temperature by 10°
\[160 + 10 = 170^\circ F\]
Step 3
Raise temperature by 25°
\[170 + 25 = 195^\circ F\]
(The added sulfur and water do not change the temperature unless specified.)
Final Temperature:
\[\boxed{195^\circ F}\]
