# PROPERTIES OF MATTER - 2024/5

Module code: PHY1039

## Module Overview

This module will introduce the classical physics that is relevant to gases and condensed matter, making use of the thermodynamic equations of state. The emphasis will be on the structure of matter and its relationship to mechanical and thermal properties, such as elasticity and thermal expansivity. Laws of classical thermodynamics will be introduced. The module will prepare the student for the study of solid state physics and advanced thermodynamics at Level FHEQ 5.

## Assessment pattern

Assessment type Unit of assessment Weighting
Coursework Bi-Weekly Small Group Tutorial Session Questions 10
Practical based assessment LABORATORY COURSEWORK 30
Examination END OF SEMESTER EXAMINATION - 2 HOURS 60

## Alternative Assessment

Assessed Laboratory Diary Mark and Report/Poster UoA may be assessed by two laboratory experiments, two diaries and two written reports.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their practical laboratory skills, abilities to analyse data and subsequently draw conclusions, skills in communicating scientific information, problem-solving abilities, and understanding of fundamental concepts & theory relating to all forms of matter

The summative assessment for this module consists of:

• Bi-weekly test questions submitted online (weighted at 10% in total).

• Laboratory coursework (weighted at 30%) consisting of:

• Laboratory diaries (every 2 weeks).

• A laboratory report or poster presentation.

• The Laboratory unit of assessment has a qualifying mark of 40%.

• A two-hour invigilated examination at the end of the semester (weighted at 60%).

Formative assessment and feedback

During the laboratory sessions, students will be given verbal feedback on their performance and written feedback on their diary-keeping from laboratory instructors.  At the poster session, students will be given verbal feedback on their poster by their peers and laboratory instructors.  At weekly tutorial classes, students will complete problem sets whose model solutions will then be uploaded on Surrey Learn.

## Module aims

• To introduce the basic principles of classical equilibrium thermodynamics.
• To introduce the Laws of Thermodynamics, and learn how to apply them when problem solving.
• To introduce the concepts of internal energy and heat, and understand their relevance in the world.
• To develop mathematical skills for use in describing thermodynamic processes.
• To relate the microscopic (atomic and molecular) structure of matter to the macroscopic properties of matter, including expansivity and elasticity.
• To reinforce concepts studied during lectures within laboratory sessions, as well as developing a range of practical and analytical skills in order to verify theory and enhance understanding. The importance of keeping an accurate and clearly-presented laboratory notebook (diary) will be stressed.

K - Subject knowledge

T - Transferable skills

P - Professional/Practical skills

## Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Equip students with subject knowledge.

• Develop skills in applying subject knowledge to physical situations.

• Enable students to tackle unseen problems in thermodynamics.

• Develop students' practical skills.

• Develop students' report-writing skills.

The learning and teaching methods include:

• 22 hours of lectures (2 hours per week for 11 weeks).

• 11 hours of tutorials (1 hour per week over 11 weeks).

• 22 hours of practical laboratory work (divided into five 4-hour sessions over 11 weeks).

The total student workload is 150 hours, with the remaining hours consisting of independent study.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

## Other information

The School of Mathematics and Physics is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas:

Resourcefulness and Resilience

Students will be asked to apply the knowledge and understanding gained during lectures in order to approach and tackle a variety of thermodynamics-based problems in small-group tutorial sessions, and subsequently submit solutions to separately-assessed problems. In addition, through a number of practical-based laboratory classes, students will need to use the concepts introduced during lectures in order to interpret and analyse data collected. They will then need to summarise these findings in the form of an assessed scientific paper/report, and present the outcome of their work in front of their peers during a scientific poster session.

Sustainability

Familiarity with the principles of thermodynamics is key to understanding the mechanisms of energy generation, and this module will explore a range of means by which energy is generated globally, and how these subsequently impact on climate and quality of life. Students will be introduced to a range of 'real-world' scenarios involving energy generation and transportation, and apply the principles and laws of thermodynamics in order to evaluate the efficiency and viability of these mechanisms, both presently and for future generations.
