Is Thermodynamics the study of the relationships among heat work and other forms of energy

Yes this is correct.

"Thermodynamics is the study of the relationships among heat, work and other forms of energy."

If 800 joules of heat are added to a gas in an isochoric process what is the change in its internal energy

800j

What is the balance chemical equation for the first law of thermodynamics

There is no chemical equation for the first law of thermodynamics, which is that energy can be neither created nor destroyed. This is a more general principle than any chemical equation.

It isn't possible to transfer heat from an object at a lower temperature to another object at a higher temperature unless

It isn't possible to transfer heat from an object at a lower temperature to another object at higher temperature unless work is done to the system. An example of this is a refrigerator.

How does water pressure affect a submarine

When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
