Fluids exist in different colors, weight, and viscosity. All throughout this week, we discussed the density, viscosity, buoyancy, hydraulics, and pneumatics. How much did you understand these subtopics? If you believe you understood much then all you have to do is take up this grade 8 tests and see if you need more study hours to properly understand the topics. All the best!
