On what principle do most thermometers work? As the temperature of the liquid in the thermometer gets hotter, the molecules move faster. As the molecules move faster, they produce greater pressure. The only free surface is the top. This greater pressure causes the liquid to expand, causing the liquid to rise in the thermometer. A. When liquid absorbs heat it loses kinetic energy. Kinetic energy = ½ * mass * velocity^2 When a liquid absorbs heat, the molecules move faster. Kinetic energy is proportional to the square of velocity of the molecules. So, since the molecules are moving faster, the liquid gains KE. B As the temperature rises, the molecules in liquid move more slowly. Temperature is the measure of the average Kinetic energy of the molecules of a substance. Let's determine what causes the temperature to rise. Suppose you half fill a small metal can with 50º F water, and place it in a pan with 120ºF water in it. The molecules of the 120ºF water are moving very fast. They collide with the atoms in the outer surface of metal can, making these atoms vibrate faster. As these atoms vibrate faster, hitting the atoms in the inside of the metal can harder, the atoms inside vibrate faster. These atoms in the inside of the metal can hit the molecules of the 50º F water, making these water molecules move faster. Since the water molecules of the 50º F water are now moving faster (greater velocity), they have more kinetic energy. So, the temperature of the water in the can is getting warmer. It is a chain reaction. C kinetic energy causes temperature? Temperature measures the kinetic energy. Kinetic energy = ½ * mass * velocity^2 Kinetic energy measures the mass and velocity of atoms and molecules. When the atoms are moving faster the temperature is higher.
Which state of matter is made up of atoms and molecules that are locked in position and can only vibrate in one place?
The state of matter described is a solid. In solids, atoms and molecules are tightly packed and locked in fixed positions, allowing them to vibrate only in place rather than move freely. This arrangement gives solids a defined shape and volume.
Readily forming diatomic molecules is a property of?
III only. Nonmetals.
Is it true that water molecules look like a chain of atoms?
No. A water molecule only consists of three atoms bonded together.
Why doesn't gases conduct heat?
Heat conductance occurs when two atoms or molecules interact with one another. This means that they must be reasonably physically close to one another. Because the density of a gas is so much lower than that of a solid or liquid, it will not conduct heat well.
A nonsolid state of matter in which the atoms or molecules are free to move past each other as in a gas or liquid?
Matter only comes in three forms; solid, liquid and gas. There is no other form of matter that allows atoms or molecules to move about freely.
How does temperature affect the molecules of a solid?
Temperature is energy. When increasing the energy, you makes the atoms move faster. As the atoms move faster and faster with increased level of energy, the atoms will react more easily with other present atoms, forming maybe "wanted" or "unwanted" molecules. Eventually the solid will melt. If still applying more heat/energy, the melted solid will turn into a gas. IF managing to still increase the energy in the material, then the gas will turn into plazma. Plazma is (due to heat mainly) not possible to contain in any container because it will melt. The only way to contain Plazma is in an magnetic field. Regards.

Why do gases do not connduct heat?
Conduction of heat is possible only in case of solids. In solids the atoms have been arranged in array forming lattice pattern. They are held up by metallic bonds. So heat conduction means the vibrational energy is transported from one atom or molecule to the other. But in case of fluids, ie both liquids and gases, there are no such bondage of atoms or molecules. So conduction is not possible, but convection becomes possible as the molecules or atoms they transfer the heat energy by transitory motion.
Do hydrocarbon molecules always contain hydrogen carbon and oxygen atoms?
No.Hydrocarbon molecules contain hydrogen and carbon atoms.It is carbohydrate molecules that contain hydrogen, carbon, and oxygen atoms.
Does heat have atoms?
Yes. The whole universe is made of atoms, I think. The air you breathe, those are oxygen atoms. The hydrogen inside the sun, those are Protium atoms. Isotopes are different kinds of an element, and Protium is one of the isotopes of hydrogen. Not all have them, Aluminum only has one type of itself.

Is heat the reason of temperature or temperature the reason for heat?
The actual energy is the heat, which represents the motion of atoms and molecules, which is a function of matter. Heat is produced when energy interacts with matter.Temperature is only a measurement of the energy stored in matter, or more technically that matter's ability to provide or release that energy.
What is the difference between interstitial and vacancy diffusion?
The main difference is atoms that which are channelled through the diffusing process where the atoms stick to the molecular structure of a material this only happens in interstitial diffusion where in vacancy diffusion the atoms reppelled away hence the word vacancy.
Are molecules in a solid loosely packed together?
solids ceep there shape beecuse there atoms are tightly pact and leav hardly any room patwn the atoms unlike liqeds with more room
Why convection cannot take place in solids?
Convection relies on the movement of fluid particles, such as air or water, to transfer heat. Since solids do not have freely moving particles like fluids, convection cannot take place within them. Heat transfer in solids typically occurs through conduction, where heat is transferred through the vibration of atoms or molecules.
State and discuss the modes transfer of heat?
The modes of transfer of heat are: # Conduction # Convection # Radiation In Conduction, heat is transferred along the material by the vibration of molecules. The molecules, however, don't actually move from their positions. It is usually seen in solids only. Heat transfer in Convection is by actual movement of material molecules. It is seen in liquids and gases. Radiation is the mode of transfer which does not need any material medium. The transfer of heat is done by electromagnetic waves.
