When a substance is melted, its particles move from a solid to a liquid state. However, when a substance is vaporized, its particles move from a liquid to a gas state, requiring more energy because the intermolecular forces holding the particles together are stronger in the liquid state compared to the solid state.
According to Einstein, E=mc^2. That is, energy equals mass times the speed off light squared. In laymen's terms, the amount of energy in an amount of mass is that mass times 300,000,000 squared.
Heating a solid substance usually increases the kinetic energy of its particles, causing them to vibrate and move more rapidly. As a result, the substance may change state, melt into a liquid, or undergo a chemical reaction if it reaches its melting or reaction temperature.
The thermal energy of particles in a substance is a measure of their average kinetic energy, which is the energy associated with their motion. As the temperature of the substance increases, the particles move faster and their kinetic energy increases, leading to a higher thermal energy. Temperature is a key factor in determining the amount of thermal energy present in a substance.
As the temperature of a substance increases, its thermal energy also increases. This leads to greater kinetic energy of the particles within the substance, causing them to move faster and creating more thermal energy.
Temperature is a measure of the average kinetic energy of particles in a substance; it does not directly indicate the total amount of thermal energy. Thermal energy is the total kinetic and potential energy of particles in a substance. While an increase in temperature generally corresponds to an increase in thermal energy, it is not a direct measure of the total thermal energy in a substance.
It takes more heat to vaporize 12 grams of CH4 (methane) compared to 12 grams of Hg (mercury) because methane has weaker intermolecular forces and a lower boiling point. This means more energy is required to break the bonds between methane molecules to allow them to vaporize. Mercury has stronger intermolecular forces, so it requires less energy to vaporize.

The energy required to sublime (solid to gas) a substance at 1 ATM pressure is greater than the energy required to melt (solid to liquid) a substance. When you compare the energies in varying pressures, however, this trend is not always the case. If you Google any 'general phase diagram', you can see that under the triple point, when all phases are in equilibrium, have solid and gas meeting under a certain pressure. In a vacuum, it would require less energy to sublime than to melt.
The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).
It would help if you could specify the substance? Would help! Hope this helped! Varian Wyrnn!
The addition of heat can change the state of a substance by providing energy to overcome intermolecular forces. For example, adding heat to a solid can melt it into a liquid, and adding more heat can vaporize it into a gas. Conversely, removing heat can cause a gas to condense into a liquid or freeze into a solid. Plasma is a state of matter where high heat energy strips electrons from atoms, creating a highly ionized gas.
Yes, thermal energy does depend on the amount of substance. The more mass a substance has, the more thermal energy it can store. This is because thermal energy is related to the internal energy of a substance, which increases with the amount of substance present.
When a substance is heated, its internal energy increases and causes the particles to move more rapidly, breaking the bonds holding them in a solid state. This results in the substance transitioning from a solid to a liquid state, known as melting. The melting point is the specific temperature at which this transition occurs for a particular substance.
Yes, the thermal energy of a substance depends on its mass because thermal energy is a form of internal energy related to the motion of particles within the substance. More particles in a larger amount of substance would have more kinetic energy, contributing to a higher thermal energy.
the higher the potential energy, the more is the stability....
"Softening" is the term used to describe the process when a solid substance begins to melt and become more pliable.
