Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

Inquiry Method Steps 1. Ask a question or identify the problem – What do you want to learn about? This question forms the starting point for inquiry. Example: You may be interested in discovering what methods of studying lead to better exam results. 2. Develop a hypothesis – A hypothesis is possible answer to your research question. Your hypothesis gives you direction. It helps you to determine what needs to be tested and which research method you will use. Example: You may hypothesize that

STRUCTURES CHAPTER SIX 6. KANIS METHOD OR ROTATION CONTRIBUTION METHOD OF FRAME ANALYSIS This method may be considered as a further simplification of moment distribution method wherein the problems involving sway were attempted in a tabular form thrice (for double story frames) and two shear co-efficients had to be determined which when inserted in end moments gave us the final end moments. All this effort can be cut short very considerably by using this method. → Frame analysis is carried out by

sampling methods. Give one example of each. Non-probability sampling Non-probability sampling is that sampling procedure which does not afford any basis for estimating the probability that each item in the population has of being included in the sample. In this type of sampling‚ items for the sample are selected deliberately by the researcher; his choice concerning the items remains supreme. Non-Probability Sampling Methods: The common feature in non probability sampling methods is that subjective
