The motion of particles is accelerated.
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
The particles move faster, bumping into each other more, causing the average distance between particles to increase.
You really need to be more careful in the way you phrase this question. I suspect the answer you are looking for is "mass" but there are potentially many other answers depending on what kind of question this is.
The total kinetic energy of the particles in a sample is a measure of the sum of the individual kinetic energies of each particle in the sample. It depends on factors like temperature and the mass of the particles. The kinetic energy is directly proportional to the temperature of the sample.
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
The average velocity of the particles in the sample. By measuring the motion of each particle and calculating the average, you can determine the typical speed and direction of motion for the particles in the sample.
You would be measuring the sample's temperature. Temperature is related to the average kinetic energy of the particles in a sample. By measuring the motion of all particles and calculating the average, you are essentially determining the average kinetic energy and thus the temperature of the sample.
The random motion of particles in a gas is associated with kinetic energy. This energy corresponds to the particles' motion and is dependent on their velocity and mass.
Using this data, you could calculate the average kinetic energy of the particles in the sample. Kinetic energy is directly related to motion and is determined by the mass and velocity of the particles. By finding the average kinetic energy, you can understand the overall thermal energy of the sample.
When particles are heated they get very energetic and try to break away from their bonds to eachother. At the start they make tiny vibrations and gradually get very fast and can turn into a liquad.
As the temperature of a gas sample increases, the kinetic energy of the gas particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in the sample. Therefore, an increase in temperature corresponds to an increase in the average kinetic energy of the gas particles in the sample.

temperature
As the individual atoms are warmed up, they move faster causing the substance to expand slightly. As a substance has energy added to it through heating, its Kinetic Energy becomes greater. Kinetic energy is the energy of Motion - the more the kinetic energy of the atoms of a substance means the faster the speed of motion of these same atoms.
Thermometers actually detect the temperature of moving particles in motion. Both mercury and alcohol (substances in thermometers) grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold.
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
