Heat energy is the stimulation of molecular motion. Anything that adds energy to a substance can increase its temperature, eventually causing molecular decomposition or a change in the phase of its elements (solid to liquid, liquid to gas, gas to plasma).
What else can I help you with?
What best describes the motion of molecules?
um .... its the kinetic energy which helps to move the molecules when the thing is hot then the kinetic energy helps the molecules move faster and when things are some what cold then the kinetic energy moves slower . the thing may be food or etc ...... .
Does Increased temperature causes a molecule to vibrate?
Yes. The molecule vibrate about its equilibrium position. If the thermal energy is high enough the molecule can break free from intermolecular bonds leading to changes i physical phase (solid-->liquid-->gas)
On what principle do most thermometers work A when liquid absorbs heat it loses kinetic energy B as the temperature rises the molecules in liquid move more slowly C kinetic energy causes temperatur?
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.
What are molecules that are joined in an ordered structure?
When molecules are linked in organized positions has solid results. When heat is absorbed by a solid the molecules vibrate faster and faster.
What happens to molecules in a solid when heat is applied?
When heat is applied to a solid, the molecules gain energy and begin to vibrate more rapidly. This increased vibration causes the molecules to have more space between them, leading to expansion of the solid. If enough heat is applied, the solid can reach its melting point and transition into a liquid state.
What does the internal kinetic energy of molecules produce?
The internal kinetic energy of molecules produces heat. This energy causes the molecules to vibrate and move faster, which generates thermal energy and raises the temperature of the substance.
Why does adding heat cause particles to vibrate faster?
Heat is a form of energy, you are adding energy to the system, this causes the particles to vibrate faster.
Does glucose diffuse faster if it is heated?
yes. When the glucose molecules gain energy, they will vibrate or move around faster.
What does heat produce?
Mechanical energy

How does your hand gets hot when you touch a hot pan?
When you touch a hot pan, the heat is transferred from the pan to your hand by a process called conduction. The molecules in the pan vibrate faster due to the heat, passing the energy to the molecules in your hand, which causes them to vibrate faster as well. This increase in vibration is perceived by your nerves as heat.
Does Increased temperature causes a molecule to vibrate?
Yes. The molecule vibrate about its equilibrium position. If the thermal energy is high enough the molecule can break free from intermolecular bonds leading to changes i physical phase (solid-->liquid-->gas)
How does light energy transform into heat energy?
When light energy is absorbed by an object, it causes the object's molecules to vibrate and move faster, which generates heat energy. This transformation occurs through a process called conversion of light energy into thermal energy.
Describe the motion of molecules of a substance change as the energy is increased?
As the energy of a substance is increased, the motion of its molecules becomes more rapid and chaotic. This increase in energy causes the molecules to vibrate and move more quickly, leading to an overall increase in temperature and pressure of the substance.
Does the more fast molecules vibrate the heat they give off?
Yes, the faster molecules vibrate, the more heat they generate. This is because heat is a form of energy related to the motion of particles. So, molecules moving faster will transfer more energy in the form of heat.
Do molecule move faster at high or low temperatures?
Molecules move faster at higher temperatures because the increase in thermal energy causes them to vibrate and move more quickly. This increased motion leads to higher kinetic energy and more frequent collisions between molecules. Conversely, at low temperatures, molecules move more slowly due to lower thermal energy.
When matter is heated does it move fast or slow?
When matter is heated the molecules in it move faster.
