Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Department of Math and Physics College of Science‚ University of Santo Tomas Abstract With the use of the ruler‚ vernier caliper‚ micrometer caliper and electronic gram scale‚ the group was able to acquire different sets of measurements by measuring the sphere of unknown composition. The group then was able to compute its mean diameter‚ average deviation‚ average deviation of the mean‚ volume‚ mass and % percent

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined

Title: Physical and Chemical Properties Purpose: The purpose of this experiment is to investigate the physical and chemical properties of pure chemical substances by subjecting them to various environmental extremes. Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included‚ heat‚ cold water‚ hot water‚ acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step. Data tables:

Introduction Wrong or inaccurate measurements can lead to wrong decisions‚ which can have serious consequences‚ costing money and even lives. The human and financial consequences of wrong decisions based on poor measurement being taken in matters as important as environmental change and pollution are almost incalculable. It is important therefore to have reliable and accurate measurements which are agreed and accepted by the relevant authorities worldwide. Metrologists are therefore continuously

Experiment 2: Laboratory Techniques and Measurements Course Number: CHE 111 Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel‚ which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric

Math Practice Lab Pre-Lab Questions: 1. The rules concerning handling significant figures are as follows: When dividing/multiplying The answer has no more significant digits than the number with the fewest significant digits (the least precise figure). Round off after calculations have been performed. When adding/subtracting Answer has no more places than the addend‚ minuend‚ or subtrahend with the fewest number of decimal places. Significant figures are irrelevant when adding/subtracting
