Laboratory Techniques and Measurements
Tiffany Abbe
Introduction:
In this lab I will be adapting more about how to utilize distinctive estimation instruments and comprehend the diverse procedures included. Figuring out how to ascertain temperature and length. Will likewise make estimations utilizing the SI frameworks for fixation, thickness, and volume. While having the capacity to reate arrangements of building so as to change focuses and densities as tock arrangement.
Materials and Methods:
The motivation behind this lab was to pick up experience utilizing different devices of estimation. The metric ruler, the advanced gram scale, the graduated barrel, volumetric cup and serological pipet were all used to catch estimations of different …show more content…
Length measurements
Object Length (cm) Length (mm) Length (m)
Cd/DVD 11 ½ 115 mm 0.115m
Keu 7cm 70mm .07m
Spoon 14.3cm 143mm 0.143m
Fork 18cm 180mm .180m
Data Table 2.
Temperature Measurements
Water Temperature (c) Temperature (f) Temperature (K)
Hot from tap 47c 116.6f 320.15k
Boiling 103c 217.4f 376.15k
Boiling for 5 mins 100c 212f 373.15k
Cold from tap 22c 71.6f 245.15k
Ice water 1 min 9c 48.2f 282.15k
Ice water 5 mins 3c 34.4f 276.15k

Mass Measurements
Object Estimated Mass (g) Actual Mass (g) Actual Mass (kg)
Pen/pencil 3g 4g .004kg
3 pennies 7.5g 8g .008kg
1 Quarter 8 7G .007kg
2 quarters, 3 dimes 20 21G .021kg

Atmospheric pressure changes with the higher sea levels, decreasing the degree at which it takes water to boil.
B. Sample 1- 0.02 % error
Sample 2--0.008% error
A.1.2g/ML
B.V = M/D
V= 26.15/19.3
V= 1.35 ml
C. Dropping the article into the water would not be fitting, in that the volume could conceivably diminish because of the danger of fluid coming out of the barrel. At the point when utilizing Archimedes rule, if the erroneous volume is dislodged, the whole result would be off base
D. Thickness = mass
19.30 g/mL = 26.15 g
Volume (mL) = 26.15 g
=1.355 mL
E. In the event that the item was dropped in the measuring glass, Archimedes' Guideline would not have been utilized by any stretch of the imagination. This is on the grounds that the guideline depends on lightness, the liquid power pushing up on the item. This power is equivalent to the heaviness of this dislodged liquid. Had we dropped.
F. The thickness estimation got utilizing Archimedes' Rule was
