If you cook a pizza on a metal tray, you place the pizza on the tray at room temperature. This is placed in a hot oven. Once cooked, you remove the tray from the oven. Eventually the tray reaches room temperature again. Describe and explain what happens to the motion of the particles in the metal tray.

1. particles vibrate

more

2. individual particles do not

get ( change their temperature).

3. They vibrate less and become

motionless

Explanation:

when the tray is placed in the oven,the particles get heated ( this results in a change in temperature.) as the temperature increases so does their kinetic energy. What this simply implies is that the particles would tend to vibrate more vigorously than before.

When you remove the tray from the oven it’s temperature decreases, so also is it’s kinetic energy. This makes the particles to vibrate slowly and become motionless.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
