. Two isolated conducting spheres are separated by a large distance. Sphere 1 has a radius of 20 cm and an initial charge30 nC while Sphere 2 has a radius of 60 cm and an initial charge 70 nC. A very thin copper wire is now connected to thespheres to allow charge to flow between them. How much charge will be transferredfromSphere 2toSphere 1? (Notethat the charge transferred can be positive, negative or zero.)

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
