Physics 3 – Sept 26, 2017 Today’s Objective – 3.2 Gas Laws lab directions: Evaluate a simple gas law. (use web to help determine gas law to evaluate: Boyle’s law, Charles’ law, Guy-Lussac’s law, Avogadro’s law, Combined gas law or Ideal gas law … it’s up to you. Explore the kinds of labs that have been done. Choose one and extend do a twist on one.) Do Now (no slip to complete) – Collect materials and get started Today’s Objective – 3.1 Thermal Physics Required Lab Agenda Finish collecting data for 3.1 Start writing/doing calcs for 3.1 Start thinking about 3.2 (time permiting) Assignment: What’s Due? 3.1 Group lab report due Oct 3 What’s Next? Think about 3 IA topic ideas for Oct 3

3.1 Objectives Use calorimetry methods to measure specific heat and latent heat. Part A – Specific heat Metals available – Copper, Aluminum, Sterling Silver, Bronze All available in 4 different masses. Styrofoam cups with cardboard caps will be our calorimeters. Temperature options: Vernier temperature probes, thermometers Consider the heat capacity of the calorimeter. To measure the heat capacity of a calorimeter you just need to add warm water to cold water in the calorimeter. Here’s how: http://www.chemteam.info/Thermochem/Video-calorimeter-constant- 02.mov
