Why do substance expand when heat energy is added to them?
Heat is a measurement of the amount of motion (or kinetic energy) of the particles of which a given substance is composed. In a solid, this motion is just a vibration, since the particles remain in place. When particles vibrate more, they will take up more space. In a gas, the particles move independently of each other, and if they move faster, they will exert more pressure and thus will tend to expand.
How do you find molecular mass if specific volume is given?
This is easy if a gas. The weight of a volume of 22.41 L will give the molecular mass.
How to identify the types of radiation given off by radioactive particles?
identify the given
What is the function of a bacterial flagella?
Flagella is the whip-like structure extending from the bacteria and it allows for movement of bacteria.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
What name is given to the movement of particles like pollen grains on a surface of liquids?
The name of this movement is Brownian motion.
What is the first invention of Einstein?
The first invention of Albert Einstein was the doctorate formula that accurately described the Brownian motion. The Brownian motion is used in Physics to explain the movement of particles in a given fluid.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
diffusion
What name was given to the zigzag motion of the particles?
It is called Brownian motion, after Robert Brown. See the related link below.
What are the characteristics of motion?
One is that it has to be defined relative to a given frame of reference.
What is streamline motion and turbulent motion?
the flow of liquid throw a pipe line is said to be stream line if at any given point , the velocity of the particles is constant.
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 does diffusion get its energy from?
Diffusion is a passive process, meaning it does not require external energy input. Instead, diffusion relies on the inherent kinetic energy of particles. The energy for diffusion comes from the random thermal motion of molecules and atoms. In other words, as particles move due to their thermal energy, they tend to spread out from areas of higher concentration to areas of lower concentration. This movement is a result of the constant random motion of particles, and over time, it leads to a more uniform distribution of particles in a given space. Diffusion occurs in gases, liquids, and solids, although it is generally faster in gases and liquids due to the greater freedom of movement of particles in these states of matter.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.

How do you calculate density from molecular weight?
the given molecular weight is divided by volume
What name is given to the movement or transporting of sediments?
Erosion is the term for the wearing away of land surfaces by weathering and transportation of particles from one place to another.
