Question #6a3b8

Answer 1

Option (d)

Explanation:

The first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant. Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed

`DeltaE_"Universe"=DeltaE_"Sys"+DeltaE_"Sur"=0`

Another form of equation that expresses this law is

`DeltaE_"Sys"=q+w" (sign convention IUPAC)"`

( Hera `Deltaq` and `Delta w` are not allowed and `Delta E` is a must)

So Option (d) is acceptable
