Chem 115 POGIL Worksheet - Week 8 Thermochemistry (Continued), Electromagnetic Radiation, and Line Spectra Why? As we saw last week, enthalpy and internal energy are state functions, which means that the sum of the heats of any set of steps that adds to give an overall reaction will have the same heat as doing the reaction directly. This is ... Changes of State In this worksheet, students will study the arrangement of particles in the three states of matter (solids, liquids and gases) followed by the explanation of how they change from one to another. With each phase change a specific amount of latent heat is released or absorbed. Below are the values in two different scales which are calories per gram (cal/g) and Joules per kilogram (J/kg). Releasing latent heat is designated as a positive number and absorbing latent heat as a negative number in this listing to make it easier to see ... a result, the energy absorbed produces changes in the potential energy of the particles, so the temperature does not change as the phase changes. For that reason, the freezing point and the melting point of a substance are the same. Base your answers to the following questions on the graph below General Directions for the LSAT Answer Sheet; Section 1; Section 2; Section 3; Section 4; Writing Sample General Directions; Writing Sample Topic; Answer Key; Computing Your Score; Sample Spanish LSAT Test; LSAT Prep Books & eBooks; Khan Academy Official LSAT Prep With each phase change a specific amount of latent heat is released or absorbed. Below are the values in two different scales which are calories per gram (cal/g) and Joules per kilogram (J/kg). Releasing latent heat is designated as a positive number and absorbing latent heat as a negative number in this listing to make it easier to see ... The multiple-choice and written-response questions in this exam can be used to test students' knowledge and understanding of specific heat, phase changes, and methods of heat transfer. This printable also asks students to interpret diagrams of conduction, convection, and radiation. Part Il: Circle the best answer, 5. 6. 8. To change from a solid to a liquid (requires heat or gives off heat). To change from a gas to a liquid (requires heat or gives off heat). To change from a liquid to a solid (requires heat or gives off heat). To change from a liquid to a gas (requires heat or gives off heat). Specific heat of a substance of unit mass is the amount of heat that is needed to raise it's temperature by 1 o C (or 1K). Mathematically specific heat is simply the ratio of the heat with the product of the temperature change and the mass of the substance.
Remember, phase changes result from energy flow. We can define a system and its boundaries and determine whether energy is going into the system or whether energy is coming out of the system. Everything outside of the system is considered to be part of the surroundings.

Fill in the phase changes in the blank provided. Phase Change Worksheet. The graph was drawn from data collected as a substance was heated at a constant rate. Use the graph to answer the following questions. At point A, the beginning of observations, the substance exists in a solid state. Material in this phase has _____ volume and _____ shape.
When the phase transition happens, that substance of matter is undergoing physical changes. In addition to the phase transitions, matter can and will undergo chemical changes based on interactions with the environment. Those chemical changes occur during different types of chemical reactions.
