TEMPERATURE AND ITS MEASUREMENTS

Temperature

Temperature is defined as the degree of hotness or coldness of a body.  The S.I unit of temperature is Kelvin.  The Kelvin scale is called the absolute or thermodynamic scale.  Other common scales of temperature are centigrade or Celsius (⁰C) and Fahrenheit (⁰F).

0 ⁰C = (0 + 273) K

The need to have two reference or fixed points of temperature called the upper and lower fixed points gave rise to different temperature scales. 

Upper fixed point: This is the temperature of steam from pure water boiling at standard atmospheric pressure. On the Celsius scale, it has the value of 100⁰C.

Lower fixed point: This is the temperature of pure melting ice at standard atmospheric pressure.  On the Celsius scale, it has the value of 0⁰C.

The interval between the upper and lower fixed points is called the fundamental interval.

Topics for SSS 1 to SSS 3 based on my Physics Scheme of Work

Recently, WAEC added some topics to the Physics syllabus in Nigeria and they started testing students on these topics in the 2014 May/June examination.  In case you are not aware, I'll advise you to download the new WAEC (Physics) syllabus here. 
These topics have been incorporated in the scheme of work that I use in school as a Physics teacher and I think it will also be nice to post the topics in my new scheme of work online.  This is because I will base all my online Physics tutorial for Senior Secondary Schools on these topics.

The topics are divided into year 10, year 11 and year 12 i.e. SSS 1 to SSS 3. The new topics are asterisked.

Download mark schemes for June 2014 IGCSE Physics

This morning, I posted the download links for Physics IGCSE (June 2014) questions. In case you did not see it, you can read and download here. As promised, here are the download links for IGCSE Physics, June 2014 questions.

For Paper 11, download here

For theory- paper 31, click here

Download alternative to practicals mark scheme here

Till next time when I'll post questions, keep visiting www.basicallyphysics.blogspot.com for Online Physics lessons.

Download IGCSE June 2014 Physics past questions papers

This is for all IGCSE students. Below are the download links for June 2014 IGCSE questions.  There are three links for the following components:

• Multiple choice - Paper 11
• Theory - Paper 31
• Alternative to practicals - Paper 61

Mark schemes will be posted around 7.00 p.m this evening.

Welcome to Physics Tutor - Your best O'level Physics blog

You are welcome to Physics Tutor.  I created this blog to serve as an avenue for Physics students to learn Physics online and I hope it is going to help a lot of students. This blog is meant for students in the following categories:

• Senior Secondary School students
• SSCE students - This includes WAEC, NECO, NABTEB and all other O'level Physics students
• IGCSE candidates
• GCE students
• All other students who are interested in learning O'level Physics

I will follow the normal school pattern when posting lessons online, though the notes will not be too voluminous.  By this I mean there are going to be lesson objectives, class tasks and home work. 
The comment box in this blog is meant for discussion/interaction.  In case you do not understand a concept, you can use the comment box so that others who understand will reply.

Solutions to tasks and assignments will also be posted.  Stay tuned to this blog.
