Air can rise in one of four ways: 1) Orographic Lifting - air travels up the side of the mtn 2) Frontal Wedging - cold, dense air acts a wedge for warm. less dense air to rise on 3) Convergence - two air masses come together, little difference in temp or density--> "collide", energy has to go somewhere--> air is forced upward 4) Localized Convective Lifting - uneven heating of Earth by sun--> pockets of warm air that rise up * As the air rises upward, it cools adiabatically until it reaches the dew point, at which point the air condenses into a cloud. Once the cloud becomes saturated with water, it rains. *

Atoms make up everything in the world around us. Some of them are radioactive, which means they emit energy in the form of ionizing radiation. Use these activities to help students learn more about atomic structure.
The principle is that the mass of matter, in a closed system, will always be the same no matter what type of change happens to the matter. Whether it's a change in state, or dissolving, or a chemical reaction, or any combination of these, the amount of mass will not change.What can occur during a physical change? ›
Physical changes are those in which the shape, size, or state of the matter changes, but the substance is still essentially the same. For example, chopping up a carrot or ice melting into water are both physical changes. Chemical changes are those where one or more substances are combined to produce a new substance.What changes occur in the particles and to their mass during a chemical change? ›
A chemical change may involve a decomposition or synthesis reaction. During a chemical change, the mass and number of atoms is conserved, but the number of molecules is not always the same. Chemical reactions involve large changes in energy. Chemical reactions are not easily reversible.What happens to the way particles are arranged in a physical change? ›
Changes in state occur because energy is either added or removed from a substance, affecting the way the particles interact with each other. If a substance is heated, energy is added and the particles will become more active; vibrating, rotating and even moving about faster.What can cause mass to change? ›
Mass always stays the same, but weight can change depending on how much gravity is acting upon an object. Cool fact: Any two masses have a gravitational attraction for one another, and the greater the mass, the greater the pull.What does mass change with? ›
Mass: The mass of an object is the amount of matter making up the object. The mass of an object can only change if part of the object is removed or more matter is added to the object.What are 4 changes of physical change? ›
Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending.What are 5 examples of physical changes? ›
Examples of physical changes: boiling water, breaking a glass, melting an ice cube, freezing water, mixing sand and water, crumpling of paper, and melting a sugar cube. Physical changes are the changes that influence the type of a synthetic substance, yet not its compound creation.What are the 3 physical changes? ›
Types of some physical changes are texture, shape, temperature, and a change in the state of matter. A change in the texture of a substance is a change in the way it feels.What happens to mass of object during physical change? ›
When a substance changes state, the mass of the substance does not change. When a substance dissolves in a liquid, the total mass of the substance and the liquid it dissolves in does not change. When substances react to form new substances as products, the mass of the products is the same as the mass of the reactants.
The number of particles does not change during a change of state, only their spacing and arrangement. As a result, the total mass has not changed. It does not matter if a substance melts, freezes, boils, evaporates, condenses or sublimates, the mass does not change.What happens to mass when an object changes state? ›
During changes of state, mass is conserved. When states change, the amount (and therefore number) of particles stays the same, meaning that mass is conserved. Only the energy and arrangement of the particles will be altered. During changes of state, properties will change.What causes the change in the arrangement of the particles? ›
Heat changes the arrangement of particles in a substance when there is a change of state.What must happen to particles in order to change physical states? ›
Matter can change from one state to another when thermal energy is absorbed or released. This change is known as change of state. The graph in Figure 11 shows the changes in temperature as thermal energy is gradually added to a container of ice. heated, it absorbs thermal energy and its temperature rises.What is a physical change in terms of particles? ›
Physical changes involve moving molecules around, but not changing them. Some types of physical changes include: Changes of state (changes from a solid to a liquid or a gas and vice versa). Separation of a mixture.Can mass change in a phase change? ›
Remember that the mass of a substance depends on the amount of molecules. Changing from solid to liquid will increase the spacing between the molecules (volume), but it will not change the amount of molecules (mass); therefore, the solid phase and the liquid phase of a sample of substance will have the same mass.Does mass stay the same during physical and chemical changes? ›
Since the law of conservation of mass is valid under all circumstances, hence, mass always remains the same, whether a substance undergoes physical change or chemical change.Is mass a physical property or change? ›
Physical properties: Matter has mass and volume, as demonstrated by this concrete block. You can observe its mass by feeling how heavy it is when you try to pick it up; you can observe its volume by looking at it and noticing its size. Mass and volume are both examples of extensive physical properties.
