FAQs (Frequently Asked Questions)
How is a vacuum cleaner able to remove dirt and debris?
It creates partial vacuums by using a fan to generate low pressure, which draws in air and particles from the surrounding area. The collected particles are then trapped in a filter or dustbin.
What is the significance of a vacuum in space exploration?
In space, there is a near-vacuum environment, which affects how spacecraft operate and astronauts live. Understanding conditions helps in designing equipment and technology that can function effectively in space.
Why do objects fall in a vacuum?
There is no air resistance to oppose the motion of falling objects. Thus, objects in a vacuum fall with the same acceleration due to gravity, regardless of their mass, as described by the principles of free fall.
How does a vacuum flask (thermos) work?
It consists of two layers of glass separated by a vacuum. This design minimizes heat transfer by conduction and convection, allowing liquids inside to maintain their temperature for extended periods.
