Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the thermodynamic principle employed?Latent heat of fusion of water for thermal energy storage
2. What is the extended cold retention period?Maintains 4°C for over 10 days without external power
3. How does it keep things cold without power?When power is on, it freezes water into ice. When power stops, the ice melts slowly, using its cooling energy to keep the fridge cold.
4. Why is it important for vaccines?Vaccines need to stay cool to stay effective. Sure Chill keeps them at the right temperature even when electricity is missing, so they don't spoil.

Thermolabile: Substances that are sensitive to heat and can degrade or lose effectiveness when exposed to it.
Cold Chain Management: The process of maintaining a temperature-controlled supply chain for temperature-sensitive products like vaccines and pharmaceuticals.
Passive Cooling: Cooling methods that do not require active energy input, relying instead on natural processes or stored energy.
Off-Grid: Describes locations or systems that are not connected to a main utility grid, such as electricity or water.
