@Jesstho.-. can you please help me!!

Answer 4

en·thal·py
ˈenˌTHalpē,enˈTHalpē/Submit
nounPHYSICS
a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
the change in enthalpy associated with a particular chemical process.

it's the total heat of a system, so definitely not A, could be B or D, but since D says system, I say it's that. Could be wrong.

Ooops, a lot of odd characters
en·thal·py

the change in enthalpy associated with a particular chemical process.

Answer 6

Enthalpy is a defined thermodynamic potential, designated by the letter "H", that consists of the internal energy of the system plus the product of pressure and volume of the system: Since enthalpy, H, consists of internal energy, U, plus the product of pressure and the volume of the system, which are all functions of the state of the thermodynamic system, enthalpy is a state function @vera_ewing Sorry, I was busy.

Answer 7

@Jesstho.-. so would the answer be B?

Answer 8

Yes, I'd say.

Answer 9

Are you sure? I can't get it wrong...
