Is the first law of thermodynamics applicable to irreversible process also.. Explain?
yes since it is law of energy balance so irrespective of the process it can be applied to any process but small change comes when we deal with reversible and irreversible processes. it can be explained in text form : please give attention to the text; CHANGE IN TOTAL ENERGY( it is sum of change in macroscopic kinetic energy and change in macroscopic potential energy and change in internal energy,U) = HEAT TAKEN BY THE SYSTEM {actually heat taken by the medium which we use often an ideal gas}(sum of heat given to the system from outside+ heat generated with in the system ) + WORK DONE BY THE MEDIUM OR SYSTEM {again it includes all kind of works such as expansion work shaft work electrical work etc. also when the process is IRREVERSIBLE it includes internal work which is consumed to overcome the friction} for reversible processes there is no dissipation of internal heat and internal work in that case we consider that the piston cylinder which we use to explain first law is frictionless . and also since they have a characteristic property of INFINITE SLOWNESS the reversible process can be considered at equilibrium at each state. For irreversible processes the heat is generally generates with in the system because we do not use the friction less piston cylinder arrangement.
Can an energy conversion be between any types of energy?
More or less - however, any energy conversion is subject to the Second Law of Thermodynamics. A simplified explanation is that there are irreversible processes in nature, and that energy converted to heat can no longer be completely converted to other types of energy.
Is forbidden based on the second law of thermodynamics?
It forbids heat to move from a cold region to a hot regions spontaneously (you have to "pump" it there - meaning you have to do work to get it to move that direction). Alternatively - it forbids any natural/spontaneous process to DECREASE the entropy of the universe.
What is the maximum efficiency possible in an energy conversion process that isn't limited by the second law of thermodynamics?
1) Any physical process is subject to the Second Law. Assuming otherwise would not be a realistic description of our Universe. 2) The maximum possible efficiency is a factor of 1 (equivalent to 100%). If some energy is wasted, as is usually the case, the actual amount will be somewhat less.
What is a statement of the second law of thermodynamics?
Every reaction in the universe increases the disorder, or entropy, of the universe. This is because energy that goes into a reaction is usable energy, but after the reaction, the energy is not usable anymore.
Is the study of thermodynamics concerned primarily with microscopic or macroscopic processes?
Thermodynamics is concerned with macroscopic processes

How can the processes of thermodynamics be reversed?
by flicking the button that says "OFF" instead of the one that says "ON"
Is the thermochemistry is used in canning?
The thermodynamics of chemistry is used in pretty much all processes.

Which two laws in the universe govern all processes involving heat and energy?
The first and second laws of thermodynamics.
Different between thermal and thermodynamics?
Thermal is an adjective, meaning to do with heat. Thermodynamics is a noun, a branch of physics to do with the thermal properties of materials, and has several laws which are the basis of design of heat engines and other thermal processes.
How do the laws of thermodynamics support that the universe came from nothing?
They don't. What they do support is that the Universe must have had a beginning. This is because, according to the Second Law of Thermodynamics, there are irreversible processes in nature - the Universe can't remain the way it is forever.
