Is it bad to leave plastic water bottles in the car?
Some researchers who study plastics recommend against drinking water from plastic bottles that have been sitting in hot places for a long time — such as a car sizzling in the sun — concerned that the heat could help chemicals from the plastic leach into the water.
Can driving over a glass bottle pop your tire?
Answer: Very seldom, if ever, can broken glass puncture a steel-belted radial tire or cause a blowout, but certain kinds of broken glass can damage a tire and cause it to fail prematurely. Nonetheless, if glass is very sharp, it can cut into the rubber tread of the tire.
How do you make a balloon bottle car?
Procedure
- Put your car down on a flat surface and give it a good push.
- Tape the neck of the balloon around one end of the other straw.
- Cut a small hole in the top of the water bottle, just big enough to push the straw through.
- Push the free end of the straw through the hole and out the mouth of the bottle.
What is a balloon powered car?
In this activity , students will make a car powered by the elastic energy of a balloon. This car converts potential energy into kinetic energy, unlike your family car which converts chemical energy into kinetic energy. Balloons are elastic and store potential energy when they are filled with air.
What can I use for wheels on a balloon car?
Wheels (Select one)
- Bottle caps.
- Candy mints (with a hole in the middle)
- CDs.
- Cardboard circles.
What direction do balloons move?
The balloon always moves in the opposite direction from the jet of air. 2. The more compressed air there is in the balloon, the more force it will have and the faster it will move. If you decrease the number of pumps (lower the air pressure), the balloon has less force and will go slower.
What happens when you release the balloon wrapped around the bottle?
This is why when a balloon is released, the high-pressure air flows out of the balloon to the low-pressure air surrounding it: “Winds blow from high to low.” The air in the balloon pushes out against the walls, keeping it inflated. When the hole is unplugged, air flows back into the bottle.
How do lungs work experiment?
The balloon at the bottom works like your diaphragm—a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. The movement of the balloon matches your breathing – when you breathe in, your lungs fill with air just like the balloon inside the bottle did.
Are lungs like balloons?
Your lungs are like the balloon and the diaphragm is like the balloon membrane at the base of you bottle. When you exhale your diaphragm relaxes which decreases the volume of your lungs and increases the pressure in your chest.
What happens when you inhale exhale?
When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life.
What are the most important organs of the respiratory system?
These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What two respiratory infections are caused by viruses?
Common viral respiratory diseases are illnesses caused by a variety of viruses that have similar traits and affect the upper respiratory tract. The viruses involved may be the influenza viruses, respiratory syncytial virus (RSV), parainfluenza viruses, or respiratory adenoviruses.
What viruses affect the lungs?
The flu virus affects the nose, throat and lungs, and can lead to serious lung infections, such as pneumonia. Other common types of respiratory viruses include rhinovirus/enterovirus, parainfluenza, respiratory syncytial virus and adenovirus.
What is the best medicine for viral infection?
The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis.Drugs used for treatment for viral fever are Acetaminophen(Tylenolothers)ibuprofen (Advil,motrin IB others).
