Kinetic Theory Of Gases Postulates of the Kinetic Theory of Gases: A gas consists of a large number of tiny particles that are in constant, random motion The gas particles occupy a net volume so small in relation to the volume of their container that their contribution to the total volume can be ignored The collisions between particles and the walls of the container are perfectly elastic (no energy transfer) Kinetic Theory of Gases relates temperature to average kinetic energy Kinetic Theory of Gases (aka Kinetic Molecular Theory) can be used to explain the Gas Laws: Pressure-Volume Relationship (Boyle?s Law) P? 1/V or V ? 1/P (at constant n, T) Pressure-Temperature Relationship (Guy-Lussac?s Law) ?T, ?v ?v, ?P Volume-Temperature Relationship (Charles?s Law)

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 06 Dec. 2012 Brady, Jespersen, & Hyslop Chapter 11 Properties of Gases Properties of Gases Compressible Low Density Exert Pressure (temperature dependence) Expand Mixable Some common properties of gases: While bulk properties, these intimate a molecular level foundation. Properties of Gases Recall that our understanding of kinetic energy in molecular systems relies on a molecular-level picture of gases. Kinetic Theory of Gases (CH 7) Example: Pressure Units of Pressure Standard atmosphere (atm): the pressure needed to support a column of mercury 760 mm high measures at 0 ?C The SI unit of pressure is the pascal (Pa): Pressure Measurements Open-ended Mercury Manometer:

Psychoactive Substance Use Disorders Definitions DSM diagnoses Abuse: continued use despite harmful consequences Dependence: specify whether physiological dependence present Problems with younger populations Problems detecting withdrawal symptoms Frequent polydrug use Developmental status decreases impairment Stages to drug dependence Experimentation Used occasionally Routine use Change their lives to involve using & getting Addiction or dependency Powerless to resist the substance Research on Adolescents Frequency and type of use Gateway drugs abstainers Risk factors Personality traits Family relationships Friends Transition-proneness Types of substances Depressants Alcohol: patterns, risk factors Opiates Stimulants Psychedelics Etiology Biological determinants

Personality Disorders Assessment Normal vs. Abnormal personality assessment Interviews vs. questionnaires Adult vs. adolescent/children Some specific instruments designed for younger populations Stability of specific diagnoses not clear (more with younger population) Article on stability indicated that trait constellations were stable but fluctuations in meeting criteria Possible that general personality disturbance more stable Classification Problems in classifying: Reliability and validity High degree of overlap Difficulty with distinctions with normal Sexism Classification Personality traits versus disorders FFM Neuroticism, extraversion agreeableness, consientiousness, openness Longitudinal relationship betwn traits & disorders ? article

Disorders involving Gender and Sexuality Influence of culture How do cultural norms influence our attitudes towards sexual behaviors? Should that be reflected in the determination of mental disorders? Gender Identity Disorder Gender Identity: One?s psychological sense of being female or male Gender Identity Disorder (transsexualism): Conflict between one?s anatomic sex and one?s gender associated with serious emotional distress or impaired functioning Not caused by ?inter-sex? condition Not confused with sexual orientation Cause: Unclear? Over identification w/mom Disturbance in endocrine (hormonal) environment during gestation? Sexual Dysfunctions Persistent problems with sexual interest, arousal, or response: lifetime vs. acquired; situational vs. generalized
