What else can I help you with?
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
The more particles a substance has as a given in what?
the higher its tempeture
The more particles a substance has at a given temperature?
the more thermal energy it has
What is the meaning of thermal velocity?
Thermal velocity can be defined as the speed at which particles move to make up a gas, liquid, or other such substance. Thermal velocity is a measurement of temperature. This is a common term used in medicine research.
Is the density higher or lower when the particles are closer in a substance?
The density is higher when the particles are closer together in a substance because there is more mass packed into a given volume. This leads to a higher mass per unit volume, which is the definition of density.
Which particles have more kinetic energy-those in a substance with a high temperature or those in a substance with a low temperature?
Particles in a substance with a high temperature have more kinetic energy than those in a substance with a low temperature. Temperature is a measure of the average kinetic energy of particles in a substance, so higher temperature means higher average kinetic energy.
Is temperature or thermal energy dependent upon the mass or amount of the substance?
It depends on its mass since the bigger the object is, the higher its heat content. Is also dependent on its temperature change since the particles of matter are in motion and the energy depends on speed thus, the faster the motion of the particles in the object, the higher the heat content is.
What is average kinetic energy of the particles of matter in a given space?
The average kinetic energy of particles in matter is directly related to the temperature of that matter. As temperature increases, the average kinetic energy of particles also increases. This energy is due to the random motion of particles within the substance.
Is it true that the more particles of an object has at a given temperature the more thermal energy it has?
Yes, the more particles an object has at a given temperature, the more thermal energy it has because there are more particles moving and vibrating. This leads to a higher overall kinetic energy of the system.
Which term describes a measurement of the movement of atoms or molecules within an object?
Diffusion is the term that describes the movement of atoms or molecules within an object. It refers to the process by which particles spread out or move from areas of higher concentration to areas of lower concentration.
Which term is defined as a measure of the energy of motion of particles in a substance?
Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.
What is determined by the distance between the particles in a given substance?
Density.
