Mr. Gill cooked a meatloaf in his oven for about an hour, and just before the meatloaf was done in the oven, he boiled hot water for tea. The meatloaf cooled down shortly after Mr. Gill took it out of the oven, but the pot of boiling water took at least a half-hour to cool down. Why?

• Water can create heat energy & releases it quickly.
• Water can contain heat energy & releases it quickly.
• Water can contain heat energy and releases it slowly.
• Water can create heat energy and releases it slowly.
