Grade: 8th A
Lab report #2
Objective:
1. – To measure mass density and volume of the clamp horder.
2. -To measure mass density and volume of the water then we can take on the straw.
3.-To find the weight of the air.
Procedure:
-To know the mass of the air we blow a balloon, we put the balloon on thebalance and we measure the air, it was 1,5g then we substract the weight of the balloon it was 1,4g and the result was 0,1g. To know the volume of the air we put it on a beaker and it was 1000ml and wesubstract the measure of the water that was 300ml and the result is 700ml, the density of it is 0,000014.
-To know the mass of the clamp hoarder we put it on the balance and the result was 80,1g.Toknow the volume of the clamp hoarder we put it on the graduated cylinder and it was 410ml, we substract the water and the result is 10ml, the density of it is 8, 1
Mass
-To know the mass of thestraw we put it on the balance and the result was 0,1g, the density of it is 0, 2.
Volume
Conclusions:
– To measure the mass of the clamp horder we have to put it on the balance and we can have it.
– Tomeasure the volume of the clamp horder we have to put water on a graduated cylinder and there it give us a measurement then we substract the measurement of the water and we have the result of thevolume of the clamp horder.
-To measure the density of the clamp holder we have to divide mass over volume and we have the result.
-To measure the mass of the air we have to blow a balloon and to measureit, then we measure only the mass of the balloon, we substract the two results of each measure and we have the mass of the air.
-To measure the volume of the air we blow an small balloon and we use abeaker, then we put water on the beaker and the balloon in the beaker ,then we have a measurement and we substract the what we have and the water that we put, and then we have the volume of the…
