Final answer:
The subject of this question is physics. Astronaut clothing worn under space suits is designed to prevent overheating using principles of physics. Lightweight materials and cooling systems help regulate temperature in extreme environments.
Step-by-step explanation:
The subject of this question is physics.
The question is referring to the development of astronaut clothing worn under space suits to prevent overheating.
This development is an example of how the principles of physics are applied in order to regulate temperature and prevent overheating in extreme environments.
The use of lightweight materials and cooling systems, such as air convection, are key factors in designing these astronaut clothes.
