Explanation:
it mainly depends upon the positive displacement principle and also kinetic energy to push water. hope this hepls!
Below is an attachment containing the solution.
100nm
Work=Force×distance
=20×5
=100nm
convection
Heat transfer by convection is caused by differences of temperature and density within a fluid.
