Shani poses as the statue of liberty for an art class. she holds a torch above her head with her right hand and a book against her side with her left hand. she holds the pose for ten minutes. at the end of the session, she mentions to her friend that it was a lot of work to pose and that her arms are really tired. which describes the work shani did while she posed?

She did no work while she posed because she did not move the torch or the book.

Explanation:

For the physics normal laws, work is given by the formula:

W=F*D

Where W represents work, F-Force and D-Distance.

For physics in order for there to be work there has to be a force applied in a certain distance, since she didn´t move the torch nor the book, she didn´t perform any job.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
