What term describes the disorder of random molecular motion?
Entropy
Absolute zero may be regarded as the temperature at which?
Molecular motion in a gas would cease
How is heat different from the temperature of a body?
Heat is the total energy of molecular motion in a substance; temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.
What is the definition of variable motion?
The definition of variable motion is direction and/or changes in speed. This can refer to anything from walking to driving a car.
What is the transfer of heat through a fluid caused by a molecular motion?
Conduction. You might wish to consult the page on wikipedia with the title 'thermal conduction'.
How do you describe the dissolving process as a result of random molecular motion?
Dissolving is when a substance has mixed into a solvent.
What is the thermal energy of a substance?
the total energy from molecular motion.
What is a thermal energy of a substance?
the total energy from molecular motion.
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
What is the theory called when a substance in motion changes in motion?
Newton's Theory.
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
Is energy faster or slower when water changes from a gas to a solid?
To condense a subject you must reduce temperature. Reducing the temperature of a substance reduces the amount of heat that the object has, which means less thermal energy. Thermal energy is the energy of molecular motion, so when you reduce it, molecular motion slows.
What happens when the temperature of a substances changes?
When the temperature of a substance changes, the amount of random thermal motion on a molecular or atomic level changes accordingly; higher temperature means faster motion. A sufficient amount of temperature change will also result in a phase change. Cooling liquids freeze, heated liquids boil, heated solids melt, and so forth.
What changes would occur at a molecular level if a liquid is placed in cool conditions?
the motion of the molecules would slow down
Which state of matter has the least molecular motion?
The solid state has the least molecular motion.
Temperature is defined as the average amount of kinetic energy in a substance or a system?
Also called the Kelvin Tempurature Scale, (The measure of average Molecular Motion) occurs within the kenetic energy of a substance
What happens to the molecular motion of a liquid as it freezes?
As the temperature of a liquid substance lowers, the molecules and atoms making up the substance slow down their movement. The also pack closer together, making the substance more rigid, turning it into a solid.
