As you go from a gas to a solid, the kinetic energy of the molecules decreases significantly. In a gas, molecules move freely and possess high kinetic energy, allowing them to collide and spread apart. As the substance cools and transitions to a solid, the molecular motion slows down, leading to a reduction in kinetic energy. In a solid, molecules are closely packed and vibrate in fixed positions, resulting in much lower kinetic energy compared to their gaseous state.

What happens when you add kinetic energy to a solid?
When you add kinetic energy to a solid the molecules won't move
What happens to the average kinetic energy of water molecules as water freeze?
As water freezes, the average kinetic energy of its molecules decreases. This is because the temperature drops, leading to reduced molecular motion. As the molecules lose energy, they begin to arrange themselves into a more structured, solid form, resulting in ice. Consequently, the overall kinetic energy of the water molecules is significantly lower in the solid state compared to the liquid state.
What is the relationship between the kinetic energy of molecules and their pysical state?
The kinetic energy of molecules is higher in the gaseous state compared to the liquid or solid state. This is because the molecules in a gas have more freedom of movement and higher average velocities. As a substance transitions from a solid to a liquid to a gas, the kinetic energy of the molecules increases.
Does the kinetic energy increases when we heat a solid at its melting point?
Of the molecules in the solid : yes. Of the mass as a whole : no.
What happens when a solid a liquid and gas when it changes its state?
When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.
What happens when you add kinetic energy to a solid?
When you add kinetic energy to a solid the molecules won't move
What is the following molecules in order from least kinetic energy to greatest?
The molecules with the least kinetic energy are in solid form, followed by liquid, and then gas with the greatest kinetic energy.
What happens to the average kinetic energy of water molecules as water freeze?
As water freezes, the average kinetic energy of its molecules decreases. This is because the temperature drops, leading to reduced molecular motion. As the molecules lose energy, they begin to arrange themselves into a more structured, solid form, resulting in ice. Consequently, the overall kinetic energy of the water molecules is significantly lower in the solid state compared to the liquid state.
What happens on a molcular level when a substance melts?
Its molecules starts vibrating more than when they were solid. Their kinetic energy are greater.
Do molecules have least kinetic energy in liquid phase?
If the molecules in question have a solid phase, for example water which goes from liquid to solid, namely ice, then least kinetic energy is the solid phase, with minimum kinetic occurring at 0 Kelvin (absolute zero).
Do molecules have the lowest average kinetic energy in a plasma?
No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.
What happens to a sheet of copper as the average kinetic energy of the copper molecules decreases?
As the average kinetic energy of copper molecules decreases, the temperature of the copper sheet also decreases. Eventually, if the temperature drops low enough, the copper molecules will lose enough kinetic energy to form a solid, and the copper sheet will freeze and become a solid metal.
Kinetic energy of a solid?
The kinetic energy of a solid is the energy associated with the motion of its atoms or molecules. It is derived from the translational, vibrational, and rotational motion of the particles making up the solid. This energy contributes to the overall thermal energy of the solid.
What is the relationship between the kinetic energy of molecules and their pysical state?
The kinetic energy of molecules is higher in the gaseous state compared to the liquid or solid state. This is because the molecules in a gas have more freedom of movement and higher average velocities. As a substance transitions from a solid to a liquid to a gas, the kinetic energy of the molecules increases.
When heat is supplied to a solid substance what happens to the energy?
When heat is supplied to a solid substance, the energy is absorbed by the molecules, causing them to vibrate faster and thus increasing their kinetic energy. This increase in kinetic energy allows the solid to eventually change phase into a liquid or gas, depending on the substance and the amount of heat supplied.
Explain by kinetic molecular theory why ice is more dense then water vapours?
By looking at the states of matter ( solid ,liquid or gas) we can determine that a giben sample will have how much energy. Molecules in solid have least kinetic energy. Molecules in vapor (gas) have highest kinetic energy. Liquids have moderatee kinetic energy.
Why doesnt a frozen puddle have kinetic energy?
A frozen puddle is solid ice with molecules that have very little movement, resulting in minimal kinetic energy. In its solid state, the molecules are locked into a rigid structure and do not have the ability to move freely like in a liquid or gas.
