Question 9

A large family lives in northern Minnesota. This family gets together for a huge dinner three times a year: on Thanksgiving, on Christmas, and on the March equinox. The Thanksgiving and Christmas dinners consist of turkey, ham, mashed potatoes, and lots of boiled vegetables. The equinox dinner is pizza. The air temperature inside the home is about the same for all three meals (70$\degree$F), yet everyone remarks about how "warm, cozy, and comfortable" the air feels during the Thanksgiving and Christmas dinners, and how "cool" the inside air feels during the March meal. Explain to the family members why they might feel "warmer" inside the house during Thanksgiving and Christmas and "cooler" during the March equinox. (The answer has nothing to do with the amount or type of food consumed.)

Accepted Answer
