What are some characteristics of a solid?
In the solid state of matter, the substance has a definite shape and a definite volume. The particles of the solid are very close together and cannot change position relative to each other.
What are some characteristics of a gas?
In the gas state of matter, the substance does not have a definite shape. Instead, the gas takes the shape of the container. The gas also does not have a definite volume and fills any volume. The particles of a gas are very far apart and move around very randomly and rapidly.
What is a chemical change?
A chemical change is a process in which two or more substances combine and form a new substance with different chemical and physical properties than the original substances. Most chemical changes cannot be reversed.
What are some indicators of a chemical change?
Some indicators of a chemical change are a change in temperature, change in pressure, the formation of bubbles, and a change in the color of a substance.
What is a physical change?
A physical change is a change that affects the form or state of a substance but not its chemical composition. Sawing a piece of wood into two pieces or boiling water are examples of physical changes.
What is the Law of Conservation of Mass?
The Law of Conservation of Mass states that the total mass that enters a process must equal the total mass that exists the process.
What is a reactant?
A reactant is a substance that enters a chemical reaction.
What is a product?
A product is a substance that exits a chemical reaction.
What is a chemical reaction?
A chemical reaction is a process in which a chemical change takes place.
What are some thermodynamic factors associated with a chemical reaction?
Chemical reactions that consume energy as a result of the process are called endothermic reactions. In this case, the bond energy associated with the products are greater than the energy associated with the reactants. In an exothermic process, energy is released as a product and the reactants have greater bond energies than the products.
What is Dalton’s Law of Partial Pressure?
This law states that in a mixture of gases that do not react with each other, the total pressure exerted by the gases is equal to the sum of the partial pressures of the individual gases.
What is an ideal gas?
An ideal gas is a theoretical gas in which the particles of the gas do not attract or repel each other, and the gas particles have mass but no volume.
What is the Ideal Gas Law?
The law relates the properties of an ideal gas. The equation for the ideal gas law is:
PV = nRT
where P = pressure (in atmospheres), V = volume (in liters), n = the number of moles, T = the temperature (in Kelvin), and R = the universal gas constant = 0.0821 (atm × L)/(mole × K)
Here are some definitions to help you in your investigation
Chemical Change – the combination of a substance with another substance to form a new and different substance
Physical Change – a change that affects the form or state of a substance but not its chemical composition
Reaction – a process that results in the chemical change of a substance
Conservation of Mass – the total mass that enters a process must equal the total mass that exits the process
State of Matter – one of the four ways that matter typically exists on Earth. They include the solid, liquid, gas, and plasma states of matter.
Solid – a state of matter characterized by having a definite shape and volume
Gas – a state of matter that does not have a definite shape nor a definite volume
Vapor – a substance in the gas phase that normally is in the liquid or solid state of matter at typical conditions
Some things undergo chemical reactions, while other things remain inert. In this simulation, you’ll determine if chemical reactions occur and state indicators that provide you with answers. Get ready to have a gas with chemical reactions.
