1.	A block of wood is so loaded that it just floats in water at room temperature. What change will occur in the state of floatation, if (a) some salt is added to water (b) water is heated? Given reason. ICSE Class 9 Physics Chapter Upthrust in Fluids,Archimedes Principle and Floataion
Answer» (a) if some salt is added no Change will OCCUR to the block of wood because the HIGHER density the heavier weight OBJECT will floats on water (b) if water is heated there will be EFFECT on the log of wood it will float on water vigorously
