Topnotch well delivered,but for the equation for part 3 ,..p*V*Cp*dT/dt You substitute dxdydz for V in the above equation and got p*dx*dy*dz*dT/dt....how does the Cp (heat capacity) not fit into this equation....please anyone who has an idea explain,I will wait 🙏
Ok so water is heated because of sunlight and water moves from lower to higher region due to density difference & (without any external motor ) . Also hot water has less density and moves up, whereas cold water has more density and stays down.
