Gas Laws

Pressure Laws – This law states that “the pressure of a fixed mass of a gas is directly proportional to the absolute temperature if the volume is kept constant”. The comparison between Kelvin scale and degrees Celsius is given by;θ0

Quantity of Heat

Quantity of Heat  –Heat is a form of energy that flows from one body to another due to temperature differences between them. Heat capacity Heat capacity is defined as the quantity of heat required to raise the temperature of a given mass

Heating Effect of Electric Current

Introduction to Heating effect of an electric current – When current flows, electrical energy is transformed into other forms of energy i.e. light, mechanical and chemical changes. Factors affecting electrical heating Energy dissipated by current or work done as current

Electrostatics II

Electric fields – An electric field is the space around a charged body where another charged body would be acted on by a force. These fields are represented by lines of force.-This line of force also called an electric flux

Current Electricity II

Electric Potential Difference and Electric Current Electric current – Electric potential difference (p. d) is defined as the work done per unit charge in moving charge from one point to another. It is measured in volts.– Electric current is the rate of flow

Work Energy, Power and Machines

Energy This is the ability to do work. Forms of energy a. Chemical energy: – this is found in foods, oils charcoal firewood etc.b. Mechanical energy: – there are four types; Transformation and conservation of energy – Any device that facilitates energy transformations is

Newton's Law of Motion

Newton’s first law (law of inertia) – This law states that A body continues in its state of rest or uniform motion unless an unbalanced force acts on it.– Inertia is the property that keeps an object in its state of
