Question

explain first law of thermodynamics?

Answer 1

"The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed."

which means : any heat or wave of energy is a conservation energy which cannot be created or destroyed .

$\huge{\bold{\underline{\mathfrac{\maroon{UrAnswer!}}}}}}$

The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.

Mathematically, this is represented as

ΔU=q+w

$\huge{\bold{\boxed{\red{WHERE}}}}}$

ΔU is the total change in internal energy of a system,

q is the heat exchanged between a system and its surroundings

w is the work done by or on the system.
