Why do pennies get dull?
When you cast a penny, the die is designed to make an even number of sides or "tails." When you get a result that is not an even number of sides, the die is biased and produces a penny with a dull, pitted surface.
The die is also biased in producing coins with more sides than are needed to make an even number of coins. The result is that a penny with more sides than needed will be less likely to reach the ground when you try to turn it, and will be more likely to be squished.

Why soaring of milk is a chemical change?
Swinging of milk's temperature can cause a chemical change in the milk's proteins. The temperature swings cause the milk to release lactose and other milk sugars.

When the milk swings to a higher temperature, the lactose and other milk sugars are released more quickly, and the milk has a harder texture.
