first law of thermodynamics- Energy can neither be created nor be destroyed but it can be transformed from one form to another form"

mathematical expression-

dq - dw=du

q is heat

w is work done

u is internal energy

Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?

The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.

How can heat do work in a thermodynamic system?

Heat can do work in a thermodynamic system by transferring energy to the system, causing the system to expand and perform mechanical work. This process is governed by the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted.


Energy can neither be created nor destroyed but can change from one form to another is what thermodynamic law?

The law you are referring to is the first law of thermodynamics, which states that energy cannot be created or destroyed in an isolated system, only converted from one form to another.


What is the difference between the first and secong law of thermodynamics?

The first law of thermodynamics (law of energy conservation) states that energy cannot be created or destroyed, only transferred or converted. The second law of thermodynamics states that the entropy (disorder) of an isolated system always increases over time, reflecting the tendency of systems to move towards thermodynamic equilibrium.
