Debbie Cao IB Chemistry 12 Pressure/Volume of Air Full Lab Write Up Introduction: According to Boyle’s Law‚ the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words‚ when the pressure increases the volume decreases. When pressure decreases‚ volume increases. This can be derived from the following equation: P1 V1=P2 V2 The common use of this equation is to predict how a change in pressure or volume will alter the

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

Components of Force Vectors Equipment: String‚ spring scales‚ 1.00 kg hooked mass‚ supports‚ meter stick‚ protractor‚ 20-N spring scales. Objective: During this lab‚ you will investigate the relationship between the angle of an applied force and the magnitude of one component. You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches
