W, - weight of the body in an unknown liquid Procedure: 1) Measure masses in the air of each irregular-shaped object. In order to perform measurements first we have to hang irregular solid on the hook which is on he left arm in the case of the classic balance or just on the hook which is part of the weighting apparatus in the case of the electronic balance. Record these values in Table of the Data & Results section of this lab to the nearest tenth. 2) Measure masses in the water of each irregular-shaped object When all solids are weighted in air then we have to place baker filled up with liquid on the special stage and we will read out weights of all solids once again; masses in water first then in unknown liquid. Record these values in Table of the Data & Results section of this lab to the nearest tenth. 3) Calculate the density and specific weight of each solid using the equations given above. Record your values in Table of this lab to the nearest tenth. Object Weight in air (N) Weight in Water (N) Density of the water (Kg/m) Density of the solids (kg/m) Specific wgt. Of the solid (KN/m) Density of the unknown liquid (Kg/m) Specific wgt. Of the unknown Liquid (KN/m) 1 2 3 4 5 80 100 120 60 60 69.7 89 109 23 57 Weight in an Unknown Liquid (N) 71 91 106 26 54
