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
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.
Which term describes a measurement of the movement of atoms or molecules within an object?
Temperature. When atoms or molecules move faster, the temperature is higher. At Absolute Zero, all movement would stop.
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 determined by the distance between the particles in a given substance?
Density.
How well a substance flows at a given temperature?
The ability of a substance to flow at a given temperature is it's viscosity. Water is not very viscus at room temperature and flows easily for example.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
What physical factors does the average kinetic energy of molecules depend on?
Correct. But I would add, this is not just a characteristic of liquids. Temperature is the average kinetic energy of the particles in any given substance, for all states of matter.
Which particles have more kinetic energy-those in a substance with a high temperature or those in a substance with a low temperature?
The quality of an answer depends in part on the quality of the question. I am guessing that we are comparing for total thermal energy at fixed given temperature, a given number of particles with a larger number of particles. It makes a difference whether the actual particle makeup stays the same. In other words, we are comparing say some number of particles of Teflon with a greater number of particles of Teflon, and NOT some number of particles of Teflon with a greater number of particles of say iron, or salt; or size A particles compared to size B particles. In that case, yes, the more particles of the same kind, the more energy. Thermal energy is proportional to the mass times the absolute temperature times the specific heat, and specific heat depends on the molecular type and arrangement.
Is temperature an element?
No, temperature is the amount of thermal energy in a given amount of a substance.
