Chapter 12, Problem 41A

Baking Explain why the baking instructions on a boxof cake mix are different for high and low elevations.Would you expect to have a longer or a shorter cookingtime at a high elevation?

Interpretation Introduction

Interpretation:

The reason for baking instructions to be different at high and low elevation needs to be explained.

Concept introduction:

Cakes baked through spectrum of temperature between $300°F$ and $400°F$ at different pressure.

Answer to Problem 41A

Baking instructions are different at different elevation because of variation in air pressure.

Explanation of Solution

At high elevation or altitude, air pressure reduced or boiling point decrease for water then cooking time is more. Probably $375°F-400°F$ is suitable temperature. Baking at a lower temperature slows or decreases the process if done at high elevation.

Conclusion

Thus, due to difference in pressure the cake is baked at different temperatures at high or low elevations.
