FAQs on Blow Hot, Blow Cold - 1 Class 5 Worksheet EVS Chapter 15
| 1. What is the concept of "Blow Hot, Blow Cold"? |  |
Ans. "Blow Hot, Blow Cold" is a concept used to describe the behavior of air when it is heated or cooled. It refers to the movement of air particles and how they expand or contract depending on the temperature.
| 2. How does heating affect the movement of air particles? | |
Ans. When air is heated, the air particles gain energy and move faster. This causes the air to expand and become less dense. As a result, the heated air rises and creates a convection current.
| 3. What happens to air when it is cooled? | |
Ans. When air is cooled, the air particles lose energy and move slower. This causes the air to contract and become more dense. The cooled air then sinks, creating a convection current in the opposite direction of the heated air.
| 4. How does the concept of "Blow Hot, Blow Cold" relate to weather patterns? | |
Ans. The concept of "Blow Hot, Blow Cold" is closely related to weather patterns. It explains how the uneven heating of the Earth's surface leads to the formation of high and low-pressure systems, which in turn influence wind patterns and weather conditions.
| 5. Can you provide an example of "Blow Hot, Blow Cold" in everyday life? | |
Ans. Yes, a simple example of "Blow Hot, Blow Cold" in everyday life is the movement of air around a radiator or heater. When the heater is turned on, the air around it is heated and rises, creating a flow of warm air. Conversely, when the heater is turned off, the air cools down and sinks, creating a flow of cool air.
