We can understand if an object is hot or cold by the sense of touch. However, it can trick us sometimes. Therefore, we use a thermometer.The temperature of an object:It is the degree of hotness or coldness of an object.Thermometer: It is a device that can be used to find out how hot an object is. In other words, we use a thermometer to measure the temperature of an object.Figure 2 Laboratory thermometer The laboratory thermometer is used to find out the temperature of the other objects such as water rather than human body temperature. It can measure the temperature from -10o C to 110oC.
Minimum-maximum thermometer: It is a thermometer used to measure the minimum and maximum temperature of the day by weather forecasters. Figure 4 Minimum-maximum thermometer Digital thermometer: It is sometimes difficult to handle a Mercury filled thermometer especially when it breaks and the mercury falls out. However, nowadays digital thermometers...
Sea Breeze
Figure 11 Sea Breeze 1. The wind blowing from the sea towards the land is called Sea Breeze. 2. During the daytime, the land in the coastal area gets heated due to the sun's radiation. 3. The sea also gets heated, however it takes more time to get heated up than the land. 4. Hence the air above the land gets heated faster than the air above the sea. 5. The hot air from the land rises above as it is lighter and the cool air from the sea being heavier takes its place. This results in the sea br...
