Chapter 16: Problem 12

To keep your hands warm while skiing, you should wear mittens instead of gloves. Why?

Short Answer

Expert verified
Mittens are better than gloves for keeping hands warm while skiing because they allow the fingers to share warmth and hence maintain a higher overall temperature.

Step by step solution

01

Understanding Body Heat Production

The human body consistently produces heat as a byproduct of metabolism, which is why body temperature stays relatively constant. When the outside temperature drops, the body redirects blood flow to the core to preserve critical organ function. However, this leaves extremities like hands more susceptible to the cold.
02

Establishing the Purpose of Insulation

The purpose of insulation in cold-weather gear like mittens or gloves is to trap body heat close to the skin, slowing its dissipation into the environment. The key to good insulation is the creation of tiny pockets of air that body heat can warm.
03

Comparing Gloves and Mittens

Gloves have separate spaces for each finger, which isolates them from each other. Mittens, however, keep the fingers together in one space. This way, the fingers share warmth and maintain a higher overall temperature.
04

Final Explanation

Therefore, mittens are more effective at keeping hands warm while skiing compared to gloves because they allow the fingers to share body heat. This makes them a better option for winter sports activity like skiing.
