PHYSICS FORM THREE TOPIC 8: VAPOUR AND HUMIDITY
Vapour The Process of Evaporation of Liquid Explain the process of evaporation of liquid Vapours These are molecules which escape into the atmosphere after liquids are heated. When a liquid is heated strongly then molecules tends to escape ( those molecules are called vapour). Most liquids evaporates at any temperature…

PHYSICS FORM TWO TOPIC 2: CURRENT ELECTRICITY
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is…
