How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
What is an example of changing the volume of a material is?
For example changing the volume of a balloon.
When you replace helium in a balloon with less dense hydrogen does the buoyant force on the balloon change if the balloon remains the same size?
Yes. The helium will seep through ths skin of the balloon, reducing its buoyancy.
Can a reference point be moving?
Yes, it can be moving...For example suppose that a bird flies by a hot-air balloon. Anyne in the balloon will see that the bird is changing position in relation to the moving balloon.
Why does a hot air balloon have less mass at the end of a trip?
The propane used to burn is used up. Significantly reducing the weight
How does changing the temperature of the gas inside a balloon affect the pressure inside the balloon?
The higher the temperature, the higher the pressure and vice versa. When the temperature rises the gas molecules move faster and hit the balloon more often and with more energy.
What do you do if while changing AC filter a balloon gets sucked into return vent?
The balloon will eventually pop, and you most likely can find its pieces at the coil if using AC, or smell rubber burning if using heater.
Why do you pretest a catheter balloon?
No you do not pretest a catheter balloon! It is not only against manufacturere recommendations but it could potentially cause harm to the patient. The catheter can cause trauma to the urethra after it's been pretested. This can in turn cause a UTI. Plus, pretesting is part of the manufacturers QC before sterilization.
What are the differences between platform framing and balloon framing?
With platform construction, walls sit on top of subflooring.With balloon framing studs run full height from mudsill to top plate.By Eliesyn Velez:I got this from cha cha!.
Jay takes a fully inflated ballon and put it n a freezer two hours later the ballon appears deflated. what is this?
The air inside the balloon has contracted, reducing internal pressure, allowing the outside air pressure to cause the wall of the balloon to collapse.
Where in Kansas was the Japanese balloon bomb found?
Bigelow, KS in Marshall County. The town was razed in preparation for the construction of Tuttle Creek reservoir in 1960.
What is a baromitor?
A barometer shows the air pressure. Its funny... in science class today I made one. INSTRUCTIONS WHAT YOU NEED Balloon Jar Tape Two straws A metric ruler (MM) Construction paper Rubber band Toothpick Scissors HOW TO BUILD Inflate and deflate the balloon ONCE Cut the neck off the balloon Stretch the main part of the balloon over the jar Put the rubber band around the balloon to secure the balloon Insert one straw into another Tape the toothpick to the straws (at one end) Tape the other end to the balloon Measure the ruler on the construction paper (find the middle and make sure you label it zero) Find a way to get the paper to stand up... the tooth pick should point to the number that the air pressure is... remember the higher the pressure... the worse the weather! Watch and ENJOY!
