. Using the principles of gas laws, buoyancy, displacement etc. explain how the Cartesian diver
works.
Research on the internet, and explain in your own words how the Cartesian diver helps you to
understand how a submarine works. Please include sources used.
Explain how it uses the scientific principles of pressure, gas laws, and the properties of fluids to
function.

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.

you didnt put any of the following

what is the question here. i think you messed up.
