A total of 150 J of work is done on a gaseous refrigerant as it undergoes compression. If the internal energy of the gas increases by 86 J during the process, what is the total amount of energy transferred as heat? Has energy been added to or removed from the refrigerant as heat?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

Convection occurs when thermal energy is transferred by the movement of
