From One to Another
Energy cannot be destroyed, and thus always has to go from one form to another. So says this law!
What is the Law of Thermodynamics?
Unlike temperature, which measures the average kinetic energy, this is the total amount of kinetic energy for a substance.
What is Heat?
I can multiply the pressure and change in volume, and make it negative to find this, which I can then add with change in heat to find this other thing. Adding the first and second answers allows me to find this third thing.
What are work done, change in energy, and change in heat?
This is the area of interest, such as where a reaction is taking place.
What is a System?
This is the result of kinetic energy associated with the motion of random molecules; measuring it yields temperature!
What is Thermal Energy?
This refers to the amount of heat needed to raise a specific substance's temperature by 1 oC; per gram, not the whole thing at once!
What is Specific Heat/Specific Heat Capacity?
If I don't have this, I can find it if I know the change in heat, mass, and change in temperature of the substance.
What is Specific Heat?
This can work on the system, provide energy to the system, receive work from the system, or absorb energy from the system.
What is the Surrounding?
This is what we call the phenomenon of energy released for bonds to form, or to be needed to break one.
This, notated as +q, shows that the energy in a system is endothermic.
What is the heat absorbed?
This is what I am trying to find when I add the mass of the system and surrounding, find the change in heat of these, obtain the molar mass of the system to find moles, and then divide the change in energy by the moles calculated.
What is Enthalpy of Solution/Molar Heat Capacity?
If I forgot to put on the lid when making a soup, it would be this kind of system, where there is a loss of mass and energy.
What is an Open System?
Position, composition, condition; the very way it exists dictates how much of this matter has.
What is Potential Energy?
This refers to the amount of heat needed to raise a substance's temperature by 1 oC; the whole system!
What is Heat Capacity?
Summing the enthalpy of all products, and then subtracting the sum of all reactants, is how you find this.
What is Enthalpy of Reaction?
This time I put the lid on, and there is no loss of mass, but there is still a loss of energy, making it this type of system.
What is a closed system?
A higher or lower this dictates whether I'll be sweating outside, or freezing inside the library, respectively.
What is Kinetic Energy?
The addition of this to heat yields the change in energy in a system; no, we don't need temperature, specific heat, or mass!
What is work done?
This is what I am trying to find when I am multiplying, switching between positive and negative, and manipulating chemical equations to find energy.
What is Standard Enthalpy of Formation?
There is no such thing as this, but it refers to a system where neither mass nor energy is lost.
What is an isolated system?
