Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth, and ...

A force can be a push or a pull. When a force is exerted on an object it can change the object's speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area.

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature. The ...

Describe the kinetic theory and use it to describe the behavior of gases. Kinetic Theory, Atmospheric Pressure and Gas Pressure: Describe the kinetic theory and use it to describe the behavior of ...

Most crystalline materials conduct heat by transferring vibrational energy as acoustic waves between atoms in an ordered lattice. External pressure forces the atoms in a crystal lattice closer ...
