When a metal lid is stuck on a glass jar, why does running it under hot water help remove it?
The metal expands faster when heated. The warm particles make them grow farther apart.
If there was something heavy pushing down on the Eiffel Tower, the pyramids, and Big Ben, which would be the last one to break, and why?
The pyramids would be the last one standing because it is shaped like a triangle, which is the strongest shape because it has a flat base that supports the structure, and the sides help to keep up the pressure.

Analyze the process of boiling water in a pot on a stove as described in the sources. You must identify exactly where conduction, convection, and radiation are happening.
Conduction: Occurs where the stove element touches the kettle, and where the kettle's metal surface touches the water.
Convection: Occurs inside the water itself as it moves in a circular pattern.
Radiation: Occurs as heat waves escape from the top of the kettle or travel outwards from the stove element.
What is a truss, and why is it important to support structures?
They possess a high strength-to-weight ratio, which helps to keep the structures up and also it to go across long distances.
