Answer 1

Sample Response: The piece of cheese melts when it’s placed on the hamburger because conduction occurs. The hamburger is warmer than the cheese, so thermal energy is transferred from the hamburger to the cheese, causing it to melt.

Answer 2

The cheese melts when Kai puts it on the hamburger because the heat from the hot hamburger causes the proteins and fats in the cheese to vibrate and break down, resulting in a more fluid texture.

Step-by-step explanation:

When Kai puts a piece of cheese on the hamburger, the heat from the hot hamburger causes the cheese to melt. The cheese is composed of proteins and fats. When heat is applied, the proteins and fats in the cheese gain energy and start to vibrate. This vibration causes the proteins and fats to break down and become more fluid, resulting in the melting of the cheese.
