1. APPLICATIONS OF THERMAL EXPANSION
OBJECT
To explore various applications of
thermal expansion.

2.  We shall take a look at the following
applications of thermal expansion
1. Consideration during constructions
2. The bimetallic strip
3. Thermometers
4. Engine Coolant
5. The Charles’s Law
6. Jar lids and power lines

3. 1. CONSIDERATION DURING CONSTRUCTIONS
 The expansion or contraction of a materials
must be kept in mind while designing large
structures.

4. 2. THE BIMETALLIC STRIP
 A bimetallic strip can be used to control
thermostats and can also be used in fire
alarms.

5. 3. THERMOMETERS
 A thermometer is also constructed on the
principle of thermal expansion.

6. 4. ENGINE COOLANT
 An engine’s coolant overflows due to thermal
expansion.

7. 5. THE CHARLES’S LAW
 Charles's law states that when pressure is
kept constant, there is a direct relationship
between volume and temperature.

8. 6. JAR LIDS AND POWER LINES
 It is an everyday experience that tight metal
lids are easy to remove after passage of hot
water over them.
 Sagging of electrical power lines is another
example of thermal expansion.
