# What is the relationship between kinetic energy and the state of the substance?

## What is the relationship between kinetic energy and the state of the substance?

The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.

## What is the relationship between the kinetic energy of molecules and the physical state of the substance they compose?

The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance.

What is the relationship between the temperature of a gas sample and the kinetic energy of the particles of a gas?

The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.

What’s the relationship between kinetic energy and temperature?

Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don’t all move at the same speed. As a subtance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.

### How does kinetic energy relate to the 3 states of matter?

Matter exists in the three major forms Solid, liquid, gas. Kinetic energy is the energy by virtue of the motion of a particle. So, kinetic energy would be greater in that state of matter in which molecules will have free movement. Complete step-by-step answer:We know, matter exists in solid liquid and gas.

### What is the relationship between molecular and energy?

the relationship between molecular motion and kinetic energy is that the faster the molcules are moving, the higher the kinetic energy is.

What is the relationship between kinetic energy of the particles and the forces of attraction between the particles?

The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles. This means that a gas has nothing to hold a specific shape or volume.

What is the relationship between the temperature of a gas sample?

Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. with k being a proportionality constant that depends on the amount and pressure of the gas.

## What is the relationship between temperature and the movement of particles?

With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.

## What is the relationship between kinetic energy and temperature?

The relationship between the average kinetic energy of the molecules in a gas sample and the temperature. A physical model which is based on a few simple assumptions. The particles are so small compared with the distance between them that the volume of the individual particles can be assumed to be negligible (zero).

How does the kinetic theory of gases work?

The key to the kinetic theory of gases is the notion that the average kinetic energy (\$$E_{\\rm k}\$$) for the particles in a gas sample is proportional to the temperature. There are two key ideas here.

Which is the best description of kinetic molecular theory?

The kinetic molecular theory(KMT) is a simple microscopic model that effectively explains the gas laws described in previous modules of this chapter. This theory is based on the following five postulates described here.

### How are molecules bound in the solid phase?

In the solid phase the molecules are closely bound to one another by molecular forces. A solid holds its shape and the volume of a solid is fixed by the shape of the solid. Liquid. In the liquid phase the molecular forces are weaker than in a solid.
