Which type of science project could be done to explain what relative humidity is?
A simple science project to explain relative humidity could involve using a hygrometer, which measures moisture in the air. Students can create a DIY hygrometer using a balloon, a straw, and a scale to observe how the balloon expands or contracts with changes in humidity. By measuring the changes in the balloon's size in different environments (like indoors vs. outdoors or during different weather conditions), students can visually demonstrate how relative humidity varies and its effects on everyday life. This hands-on approach helps to solidify the concept in a tangible way.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Explain why the speed of sound changes if the temperature of the medium changes?
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
Why using 2 manipulated variables in an experiment would not be wise explain?
Well, when something changes, you would not know which variable caused the change in the experiment.
How do you explain sound to no hearing voice?
Explain vibrations, which they can feel. Then explain that sound is vibrations carried through the air.

When a body is moved from sea level to the top of a mountain what changes the body's mass it's weight or both explain?
When a body is moved from sea level to the top of a mountain, its weight changes but its mass remains constant. Weight is the force of gravity acting on an object, so as the body moves to higher altitudes where gravity is weaker, its weight decreases. Mass, on the other hand, is the amount of matter in an object and doesn't change with location.
Ideal gas law to explain why a hot air balloon floats?
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
Where is the birthplace of the scientist whose principles explain hot air balloon flight?
my backyard.
When you rub an air filles balloon with your dry hair and press it against the wall . Explain why?
Rubbing the balloon against your dry hair transfers electrons from your hair to the balloon, giving the balloon a negative charge. When you then place the negatively charged balloon against the wall, it creates an attraction with the positive charges in the wall, causing the balloon to stick due to static electricity.
How did suess explain the formation of mountain ranges?
Dr. Seuss did not explain the formation of mountain ranges. He was a children's author and illustrator known for his whimsical stories and imaginative characters, not for scientific explanations. Geologists study processes like tectonic plate movements and erosion to explain the formation of mountain ranges.
Which law explain why does the balloon loses air flies around the rooom?
The principle of air pressure explains why a balloon loses air and flies around a room. When the balloon is filled with air and released, the higher pressure inside the balloon compared to the lower pressure in the room causes the balloon to move in the direction of lower pressure until equilibrium is reached.
Why is important for moving and handling tasks to be carried out following specialist training?
explain why it is important for moving and handling tasks to be carried out following specialist training
What happens to the volume of the balloon that is taken outside on cold winter day explain?
The volume of the balloon will decrease when taken outside on a cold winter day. This is because the cold temperature causes the air inside the balloon to contract, making it occupy less space.
To describe explain and predict changes in the price and quantity of goods sold?
Laws of Supply and Demand explain and predict changes in the price and quantity of goods sold.
