What happens to molecules when they change from a sloid into a liquid?
The molecules gain energy so they break up the solid structure and move more freely, however, they still have some attraction. More energy is required to weaken this attraction This molecule to molecule attraction is weakest in gaseous state of matter
What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
Chlorophyll molecules are essential for absorbing solar energy to carry out photosynthesis. These molecules are found in the chloroplasts of plant cells and are responsible for capturing light energy and converting it into chemical energy to drive the process of photosynthesis.
Is more energy used to melt ice or freeze water?
The energy required is the same. It is the energy required to rearrange the molecules from one state to another.
Why is energy required to evaporate a liquid?
Energy is required to evaporate a liquid because the molecules in the liquid need to overcome the intermolecular forces holding them together. This energy is used to break these forces, allowing the molecules to escape into the gas phase. The absorbed energy increases the kinetic energy of the molecules, enabling them to break free from the liquid's surface and become vapor.
What heat energy required to break the attraction of liquid molecules is the heat of?
vaporization
What Heat energy required to break the attraction of liquid molecules is heat of?
vaporization

What is the energy required to overcome the attraction of protons in the nucleus and remove an electron from a gaseous atom?
The energy required to remove an electron from a gaseous atom is called the ionization energy. This energy depends on factors such as the atomic structure and the strength of the attraction between the nucleus and the electron. The higher the attraction, the higher the ionization energy needed to remove the electron.
The energy required to overcome the attraction of the nuclear charge and remove an eectron from a gaseous atom is called?
The energy required to overcome the attraction of the nuclear charge and remove an electron from a gaseous atom is called ionization energy. This energy is measured in electron volts (eV) or kilojoules per mole (kJ/mol). It represents the strength of the bond between the electron and the nucleus.
Why do low temperatures and high pressures required to liquefy chlorine gas?
Low temperatures are required to reduce the kinetic energy of the chlorine gas molecules, causing them to come closer together and form a liquid. High pressures help to further compress the gas molecules, increasing their attraction and facilitating the liquefaction process. Together, low temperatures and high pressures create conditions where the intermolecular forces dominate over the kinetic energy, allowing the gas to turn into a liquid state.
What is the energy of motion of molecules called?
Kinetic Energy
Why does it take 80 calories to convert 1 gram of water to 1 gram of steam?
Water molecules attract each other; energy is required to overcome that attraction. In other words, the change of phase implies a change in potential energy.
When molecules collide and transfer energy it is called what?
When molecules collide and transfer energy, it is called a collision.
Why molecules of a substance in a gaseous state attain free movement?
Different atoms and molecules have different degrees of attraction for other atoms and molecules in their vicinity. They also have different degrees of kinetic energy, which is measured by temperature. In other words, hot atoms and molecules have faster motion or vibration than cold ones. If the kinetic energy exceeds the attraction, the molecule or atom flies off on its own. If the attraction exceeds the kinetic energy, the molecule or atom remains glued in place.
What energy is heterotrophs required in?
nutrient molecules are broken down
