What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
When ice melt to become waterwhich force must be overcome?
The force of attraction between the water molecules in the ice must be overcome in order for the ice to melt and become water. This force is known as the hydrogen bonding between water molecules, which holds the solid ice structure together.
Why do opaque materials become warmer when light shines on them?
Opaque materials become warmer when light shines on them because they absorb the light energy and convert it into heat. The absorbed light energy excites the particles within the material, causing them to vibrate and generate heat. This increase in thermal energy raises the temperature of the material.
What is the difference between matter changes and chemical changes?
Matter changes involve physical alterations in substances, such as changes in state (solid, liquid, gas) or shape, without altering the chemical composition. Chemical changes, on the other hand, involve the formation of new substances with different chemical properties due to the rearrangement of atoms and molecules.
Does cold air fall?
Cold air sinks because it is more dense than warmer air. The warmer the air is the more energy the molecules have. The more energy the molecules have the more they vibrate. When the molecules vibrate they bounce into each other and push apart from each other, hence the warmer air is; the less dense it is (number of molecules per unit volume). So, colder air has less energy which means more molecules can fit into one space (because they are not bouncing off each other) which essentially makes it heavier.Read more: Why_doesn't_cold_air_rise
What must molecules do for. Matter to become warmer?
move faster.
What must molecules do matter to become warmer?
move faster.
What must molecules do for matter to become warm?
Molecules must gain kinetic energy, which increases their movement and vibrational activity. This increased motion causes friction and interactions between molecules, leading to an overall rise in temperature.

Why do all states of matter have molecules?
All states of matter consist of particles that are constantly moving. In solids, molecules are tightly packed and vibrate in place, in liquids molecules move around each other more freely, and in gases, molecules move independently and have more space between them. Thus, all states of matter have molecules as they are made up of these particles.
What are small molecules that must combine with large proteins to become immunogenic?
Small molecules that must combine with large proteins to become immunogenic are called haptens. Haptens alone are not immunogenic, but when they bind to proteins in the body, they can elicit an immune response.
Is smell matter?
Yes it is matter. Since the receptors in your nose only respond to molecules, the "smell" of perfume must be matter in order to activate these receptors. The liquid in perfume is atomized by the pump, physically separating the molecules. The "smell" that you are sensing is the vaporization of aromatic organic molecules from the liquid.
What does something need to have in order to be matter?
In order to be considered matter, something must have mass and occupy space. The basic building blocks of matter are atoms, which combine to form molecules and create the different substances we encounter in our everyday lives.
How do scientists define matter?
Scientists define matter as anything that has mass and occupies space. Matter is composed of tiny particles called atoms and molecules, which interact to form various substances in the universe. It includes everything we can touch, see, and measure.

Anthing that takes up space and has mass?
The object must be made up of matter to take up space and have mass. Examples include atoms, molecules, cells, and various objects such as furniture and rocks.
