What happens to the molecules of a substance as it moves from liquid state to solid state?
The molecules of the substance lose energy and usually assume a fixed lattice shape (which may be a crystalline form or an allotropic form, dependent on temperature and pressure). Some compounds such as glass (various silica compounds) can transition to an amorphous solid (non-crystalline phase) that can be fractured, but also may very slowly flow above a particular temperature (vitrification).

How does heat moves through liquid and gases?
Heat moves through liquids and gases primarily through convection. This process involves the transfer of heat energy through the movement of the molecules within the substance. As the substance is heated, the molecules gain energy and move around, carrying heat from one area to another. Additionally, in liquids and gases, heat can also be transferred through conduction and radiation, but convection is the dominant mechanism.
When thermal energy moves out of a substance the temptarue will increase or decrease?
When thermal energy moves out of a substance, its temperature will decrease. Thermal energy is the internal energy of a substance due to the kinetic energy of its atoms and molecules. As thermal energy leaves the substance, the average kinetic energy of the particles decreases, leading to a drop in temperature.
What is a substance in which a wave moves?
A medium is a substance through which a wave can move. This medium can be solid, liquid, or gas. The wave causes the particles of the medium to vibrate and transfer energy.
What happens when two substances that have different temperatures touch each other heat moves from one to the other by what?
When two substances at different temperatures touch each other, heat is transferred from the hotter substance to the cooler one through a process called conduction. This transfer of heat occurs as the molecules in the hotter substance collide with those in the cooler substance, transferring energy and causing the temperatures to equilibrate over time.
Does friction happen in a liquid?
Yes, friction can happen in a liquid. When an object moves through a liquid, such as water, the liquid molecules provide resistance to the object's motion, creating a force opposing its movement. This resistance is known as viscous drag, and it is a form of friction that occurs in liquids.

What occurs when a substance moves from liquid to gas?
This change of phase is called vaporization and is a physical phenomenon; the chemical nature of the molecules was not changed.
How is viscosity afected by temperature?
viscosity is roughly defined as how fast a liquid moves. temperature affects this level on a molecular level. when something is brought below its freezing point, it turns to a solid, meaning its atoms come as close together as possible. raise the temperature, and it becomes a liquid, meaning the atoms bounce freely, but are still held together. raise it even more, and the substance becomes a gas, and will dissipate. viscosity measures the liquid state. when a substance is near freezing, its molecules move very slowly, and the substance also moves more slowly. if you heat it to near boiling, the opposite happens, the molecules move faster, and are 'more loose', and the substance 'moves faster.'
What happens to the particles of a liquid as the liquid evaporatēs?
it moves much much faster
What happens when light moves from solid to liquid?
kill
When you heat a solid and it melts becomes a?
It becomes a liquid. solid, liquid, and gas are relative terms defining the movement of molecules, solid moves slow, liquid faster, and gas the fastest. molecules move constantly.
What happens to the molecules in a sovelent when it heats up?
They speed up and moves faster and faster.
What substance moves by osmosis?
Water is the substance that moves by osmosis. Osmosis is the movement of water molecules through a semipermeable membrane from an area of high water concentration to an area of low water concentration.
Why is the meting and freezing point of a substance the same?
The melting and freezing points of a substance are generally the same because they represent the temperature at which the solid and liquid phases of a substance are in equilibrium. This means that at the melting point, a solid changes to a liquid, while at the freezing point, a liquid changes to a solid.

What is the difference between condensation and boiling?
Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
