States of matter
Molecules in a solid
Molecules in a solid can vibrate but without changing their position. What is the relationship between temperature and the kinetic energy of the molecules? Change the temperature to find out.
Molecules in a liquid
Las moléculas de un líquido pueden cambiar su posición, pero el volumen del líquido no cambia.
Molecules in a gas
The molecules of a gas move at high speed in any direction. What determines the volume of the gas?
States of Matter
Look at the different types of molecules that make up a solid, liquid, or gas. Add or remove heat and see the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram change in real time. Relate the interaction potential of forces between molecules.
