When heat energy is transferred to an object, its temperature

increase depends upon:

1. The mass of the object

2. The substance the object is made from

3. The amount energy transferred to the object.

For a particular object, the more heat energy transferred to it,
the greater its temperature increase.

Measuring temperature

Types of temperature scales

There are two types of temperatures scales namely;
Centigrade or Celsius scale

Fahrenheit scale
On the centigrade scale, the freezing point or the lower fixed

point is 0°C and the boiling point or the upper fixed point is

100°c.

On a Fahrenheit scale, the freezing point or the lower fixed

point is 32°F and the boiling point or upper fixed point is 212°

Thermometers

A Thermometer is an instrument which is used to measure
temperature.

Types of Thermometers

 Clinical thermometer

 The Six’s minimum and maximum thermometer
 The Ordinary (wall) thermometer
