What happens when a substance is cooled?
When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
What is particle theory matter?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
Why do large particles move slower?
Larger particles move slower, due to their larger mass and may be influenced by numerous collisions with many nearby smaller particles. Hotter particles move faster because they have more energy. The rate of diffusion increases as temperature increases because the particles move faster.
Do larger particles move faster than smaller ones?
Larger particles move faster than smaller ones and thus collide more frequently and more forcefully. Chemical reactions progress at a faster rate when the reacting particles are present in higher numbers.
What is the sixth state of matter?
The fermionic condensate is a cloud of cold potassium atoms forced into a state where they behave strangely. The new matter is the sixth known form of matter after solids, liquids, gases, plasma and a Bose-Einstein condensate, created only in 1995.
What is a solid and liquid called?
A phase change is a change in the states of matter. For example, a solid may become a liquid. This phase change is called melting. When a gas changes into a liquid, it is called condensation. When a liquid changes into a solid, it is called solidification.
Is plasma a fire?
The bottom line is that a flame only becomes a plasma if it gets hot enough. Flames at lower temperatures do not contain enough ionization to become a plasma. On the other hand, a higher-temperature flame does indeed contain enough freed electrons and ions to act as a plasma. A candle flame is therefore not a plasma.
