Liquids do not have a fixed shape but they do have a fixed volume. The particles are very close together.

Pieces of dry ice (solid carbon dioxide) become smaller through the process of condensation. Particles in a liquid move around just as freely as particles in a solid.

In an ice cube, water molecules are arranged in a crystalline form. When the temperature of the water molecules reaches 0°C, the melting point of water, the molecules vibrate so fast that they break free from their fixed positions and the ice begins to melt.

A glass is a transparent fusion product inorganic substances that have cooled to a rigid state without crystalizing. The irregular internal structures of glasses are intermediate between those of a crystalline solid and those of a free flowing liquid.

How do the positions and movements of particles in a liquid help to explain the shape and volume of the liquid. the particles in a liquid are tightly packed together and move past each other allowing it to flow, and because it flows Liquids does not have a definite shape, it has a definite volume.

Fixed shape means that that state of matter will not change its shape under any changes in condition (volume/pressure/temperature).

Solids. A solid is in a state of matter that maintains a fixed volume and shape. A solid’s particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate.

The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.

Plasma is not a gas, liquid, or solid – it is the fourth state of matter. “99.9 percent of the Universe is made up of plasma,” says Dr. Dennis Gallagher, a plasma physicist at NASA’s Marshall Space Flight Center. “Very little material in space is made of rock like the Earth.”

Our sun is essentially a big ball of hot plasma — an energetic state of matter made up of ionized gas. As the sun spins, the plasma spins along, too. This plasma movement in the core of the sun produces a magnetic field that fills the solar atmosphere.

The Sun and stars consist of very little actual hydrogen and helium gas. Because the temperatures are so high, the atoms are nearly completely ionized into hydrogen ions and helium ions, ie. a plasma.

Top: Lightning and neon lights are commonplace generators of plasma. Depending on temperature and density, a certain amount of neutral particles may also be present, in which case plasma is called partially ionized. Neon signs and lightning are examples of partially ionized plasmas.

Answer: The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.

The sun is made of Helium, Hydrogen and small amounts of Carbon, Nitrogen and Oxygen. The sun looks like it’s on fire because whats happening in its so called “surface” are nuclear explosion that keep happening and thats also why it emits so much radiation.

The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion. At the same time, hydrogen atoms in the fuel bond with oxygen atoms to make water molecules.

No. The surface of the sun is approximately 10,000 degrees Fahrenheit while a wood burning fire is about 600 degrees Fahrenheit.

The hottest flame ever produced was at 4990° Celsius. This fire was formed using dicyanoacetylene as fuel and ozone as the oxidizer. Cool fire may also be made. For example, a flame around 120° Celsius may be formed using a regulated air-fuel mixture.
