they spread apart and move faster when energy is added.
When heat is added to a substance, the molecules and atoms vibrate faster.
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
No, in freezing, energy is actually removed from a substance. As the temperature drops, the molecules within the substance slow down and come closer together, eventually forming a solid state. This process releases energy in the form of heat.
When heat energy is added, the speed of the molecules increases. This increase in speed leads to a higher kinetic energy and results in a rise in temperature of the substance.
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
As energy is added and temperature increases, molecules gain kinetic energy and move more rapidly. This increase in movement can lead to stronger molecular interactions, changes in molecular configuration, and ultimately a change in the state of matter (e.g., from solid to liquid or gas).
When heat is added to a substance, its molecules gain energy and move faster, causing the substance to increase in temperature. This can lead to changes in physical state, such as melting or boiling, depending on the substance's properties. In some cases, chemical reactions may also occur due to the increased thermal energy.
Evaporation requires heat energy to be added because it provides the molecules in a substance with enough kinetic energy to overcome the attractive forces holding them together. As molecules gain energy, they move faster and escape the liquid phase, transitioning into the gas phase. This process leads to evaporation.
When you heat molecule you give them energy in form of motion.Lets take CO2 molecule. When you heat it its velocity increases. Particles start flying faster. Second thing that happens is that bonds O-C-O starts vibrate more rapidly and stronger (at some point thous vibrations can torn apart molecule)So two things happen to molecule when you heat them:You increase theyr velocityYou increase vibration of bondsthe molecules start moving faster.
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
The direct cause of a substance's temperature increase is the input of thermal energy, typically in the form of heat. This added energy increases the kinetic energy of the substance's molecules, causing them to move faster and leading to an increase in temperature.
As heat is added to a substance, the particles in the substance gain kinetic energy and move faster. This increased movement causes the particles to vibrate and collide more frequently, leading to an expansion of the substance.
