J8. over several cycles, a refrigerator compressor does work on the refrigerant. this work is equivalent to a constant pressure of 413 × 105 pa compressing a circular piston with a radius of 0,.019 m a distance of 25.0 m. if the change in the refrigerant's internal energy is 0 j after each cycle, how much heat will the refrigerant remove from within the refrigerator?

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).
