Thermos bottles and ice chests utilize insulation to maintain the temperature of their contents. Thermos bottles typically have a vacuum seal between two walls, which minimizes heat transfer by conduction and convection, keeping liquids hot or cold for extended periods. Ice chests use thick foam insulation and airtight designs to reduce heat exchange, allowing ice to melt more slowly and keeping food and drinks cold. Together, these features effectively preserve the desired temperature of the items inside.
