The first law of thermodynamics is usually written as dq=dw+du. you need to look at the signs carefully; some other disciplines (chemistry comes to mind) may use other signs, which implies other definitions of these quantities.

The first law of thermodynamics is follows the quantity dQ = dW + dU where Q is the heat flow, W is the work and U is the internal energy. Only the internal energy is a state function where it means that it does not follow a specific path to arrive at a certain number. Whereas the work and heat are not state functions and they follow a specific path or process in order to arrive at a certain number. An example would be  if you are given 2,380 J of energy to do work as 12,900 J and you are to find the internal energy. Apply the equation above:

Q = U + W
2,380 J = U + 12,900 J
U = 15,280J.

Hello we have the same names lol.biology is the study of living beings , that is, all plants and animals including humans.

Because the earth is not round ,but it may seem round when viewed from ,our planet but true some points earth is not round was an oblate spheroid -a square that it squashed as globe however is not even a perfect oblate spheroid.in fact isaac newton's first proposed that earth was not perfectly round but it was an oblate spheroid instead.that mean a square that is squashed as its poles and swollen at the
