What are variables for the first law of thermodynamics?
the internal energy (thermal energy)
Why you study thermodynamics?
Thermodynamics is the branch of physics that deals with the study of energy transport. Thermodynamics is one of the most important sectors of mechanical engineering. The three theories of thermodynamics state that matter and energy are not created nor destroyed, they are only altered.
Which choice best explains what internal energy is as it relates to the first law of thermodynamics?
Internal energy is the sum of the randomly distributed microscopic potential energy and kinetic energy of the molecules that make up the system. The first law of thermodynamics states that: "The internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." The first law of thermodynamics is a direct consequence of the principle of conservation of energy.
Could you review the laws of thermodynamics?
Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they must be in thermal equilibrium with each other. This law helps define the notion of temperature.First law of thermodynamics: Heat is a form of energy.Because energy is conserved, the internal energy of a system changes as heat flows in or out of it. Equivalently, perpetual motion machines of the first kind are impossible.Second law of thermodynamics: The entropy of any closed system not in thermal equilibrium almost always increases.Closed systems spontaneously evolve towards thermal equilibrium -- the state of maximum entropy of the system -- in a process known as "thermalization". Equivalently, perpetual motion machines of the second kind are impossible.Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches zero.The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has
What type of energy is thermodynamics the study of?
The energy of motion and heat.

What happened to Lost?
Well, thermodynamics is the science that studies this. According to the the first law of thermodynamics, all energy in all forms are conserved. The main types of energy we consider is kinetic, potential and internal energy. You may not be familar with Internal energy but it is another form of energy that we lump the energy of chemical bonds and kinetic and potential energies (ON THE MOLECULAR LEVEL) into it. Internal energy is proportional to the temperature of the object.

What studies are required to be able to work with alternate energy?
thermodynamics, heat transfer... and the course is Mechanical Engineering...

What is the significance of first law of thermodynamics?
ti introduces the concept of internal energy and it tells that one form of energy can beconverted into another form
What branch of science involves the study of all forms of energy?
For thermal energy it is thermodynamics, for mechanical energy it would be mechanics or mechanical engineering, for electrical energy electrical engineering, and for nuclear energy, nuclear physics. There doesn't seem to be one branch of science for energy as a whole.
What type of energy is thermodynamics the study of?
The energy of motion and heat.
A balance between the weight of a layer in a star and the internal energy pressure that supports it is?
hydrostatic equilibrium
A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.
What is the energy transferred from a hotter object to a cooler one is referred to as?
This is the zeroth law of thermodynamics: objects at different temperatures will form a thermal equilibrium. The first law of thermodynamics says that energy can not be created or destroyed but can only change form. So the cooler object has to get hotter not the other way around.
