Solid State Physics

A gas will expand to fill up the container it is in because the particles are free to move and have a lot of kinetic energy. Solids and liquids have more compacted particles and won't expand to fill the container.

Metals are generally good conductors of both electricity and heat. Insulators do not conduct electricity or heat because their electron lattice has no free electrons. The heat of your hand is conducted away much faster when a metal is touched. Eventually the metal heats up to your body temperature and if touched again will feel the same as an insulator.

Try putting an ice cube on a square of black plastic and another one on an identical looking square of thick aluminium. The result is amazing.

a 1.00 x10^4 meter steel railroad truck with the coefficient of linear expansion of 12x10^-6 per degree celciuos changes temperature from 18c to 38c . by how much many meters will the railroad truck expand?

It actually has more than one LED inside the same package. For instance, a package with red, green and blue LEDs inside can produce any color by mixing these three colors together.

Diopter is the unit of the power of lens

2. Energy can change from one form to another. This is called an energy conversion or energy transformation.

• The Law of Conservation of Energy states that energy can change form, but it cannot be

created or destroyed. Therefore, the total amount of energy stays the same.

• In energy transformations, some energy is always lost to the environment as thermal energy.

Examples of energy transformations and their uses:

· A television changes electrical energy into sound and light energy.

· A toaster changes electrical energy into thermal energy and light.

· A car changes chemical energy from fuel into thermal energy and mechanical

energy.

· A flashlight changes chemical energy from batteries into light energy.

· Solar energy is converted into electrical energy using solar panels.

· Campfires convert chemical energy stored in wood into thermal energy, which

is useful for cooking food and staying warm.

This is the way we describe the ductility of metals. A ductile metal can be "pulled" (called "drawing" by the industry) and made into wire, or rolled and turned into foil. Copper is drawn into wire and aluminum is rolled into foil, and both metals will stand up to the processes because they have the physical property of ductility. Look below for links.

No, magnetic domains are a phenomenon that only occurs in ferromagnetic materials.

Decrease in temperature and increase in pressure.

work = the exerted force x the distance over which it was exerted

w= f x d

force is measured in newtons (N)

distance is measured in meters (m)

therefore w = M x N a.k.a. joules

Work is measured in Joules (J)

ash is a solid

A fat can be a solid or a liquid. Normally we refer to a liquid fat as an 'oil', but this is for a fatty compound that is liquid at room temperature. All fats can be liquified or solidified, and will still be called 'fats' no matter what.

Yes. If the termals are connected by wires, charges will flow from one end to the other.

14 Bravais lattices are known and 230 space groups.

A month is formed based on the cycle of the moon around the Earth. It takes about 29.5 days for the moon to complete one orbit, which is why most months have around 30 days. Our calendar system further refines this cycle into months of 28-31 days to align with the solar year.

SnCl2 is solid because it has a higher melting point due to its crystal lattice structure, which is more stable in the solid state. SnCl4 is liquid at room temperature because it has weaker intermolecular forces between its molecules, allowing them to move more freely and thus exist in a liquid state.

No

From Wikipedia: "Supercooling, also known as undercooling, is the process of lowering the temperature of a liquid or a gas below its freezing point without it becoming a solid."

It means that the integral is calculated along a given line, which may be curved.
