Find the answers to the “Microsoft Rewards Bing Supersonic Quiz” for 5-20-2025. Learn the science behind insulated mugs and how they keep drinks hot or cold.
Question 1: What is the main function of a vacuum in insulated mugs?
- Cools the drink
- Adds extra heat
- Prevents heat transfer
Answer: Prevents heat transfer
Fact: The main function of a vacuum in insulated mugs is to prevent heat transfer. The vacuum layer between the inner and outer walls blocks heat from escaping or entering. This keeps hot drinks warm and cold drinks cool for a longer time. Since there’s no air in the vacuum, heat can’t travel easily.
Question 2: What material is commonly used inside insulated mugs?
- Stainless steel
- Wood
- Plastic
Answer: Stainless steel
Fact: The material most commonly used inside insulated mugs is stainless steel. It is strong, does not rust, and keeps drinks hot or cold for a long time. Some mugs may also have plastic parts, but they are usually on the outside or the lid. Wood is not commonly used inside because it doesn’t insulate well and can absorb liquids.
Question 3: Why do some insulated mugs have a copper lining?
- To keep drinks fizzy
- To reflect heat
- To change color
Answer: To reflect heat
Fact: Some insulated mugs have a copper lining to reflect heat and improve insulation. Copper is a good thermal reflector, so it helps keep hot drinks hot and cold drinks cold for a longer time. It doesn’t change the color of the mug or make drinks fizzy. The copper lining simply improves temperature control.
