Important
1. A gas trapped in a cylinder does 540 J of work by expansion. At the end of the
process, the internal energy has decreased by 860 J.
a. How much energy was transferred as the heat between the gas and its environment?

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i think it's 35 meters
