What are observations and measurements called?
Usually, when observations and measurements are aggregated, these are called DATA.
Will CO2 make a balloon float?
Yes it will, if it's inside the balloon and hot enough.
It actually won't. CO2 is a heavier gas than Earth's atmosphere, so it will sink. Think about it- we breathe out carbon dioxide, and balloons we blow up the normal way don't float.
Will an object with a density of 2 float in water?
No. Objects will only float in water with a density that is less than 1. This is not always true if another substance is in the water, such as salt.
Which transparent material is made of sand?
Common glass is made from clean sand, soda, and limestone. Various other elements may be added to modify the properties of the glass - colour, density etc.
Can recycled newspaper fertilize plants?
if composted; yes.
it's also a great weed control.
With my garden, I mulch up the newspaper [and junk mail] in lots of water; allow it to break down to the point that it's almost like plaster; then throw it on the garden [about an inch and a half thick] after I've tilled and fertilized. then I punch holes through it to plant.
it's a little ugly at first, but blends in after a while. You can also throw down mulch or wood chips to cover the paper.
Beats weeding!
then next year I till it all back in and it works great.
Actually, in the fall I till; and then again in the spring.
kills 2 birds with one stone.
How many muscles do you use in a backhandspring?
A back handspring takes muscles in your upper arms, core, and thighs, and possibly lower arms and legs, too. Just because you don't think you're very strong in these areas, however, doesn't mean you can't do the handspring, because you develop the necessary flexibility and strength when you start to learn and practice for the move.
Science fair project with crayons?
You could melt different types of crayons to see which color melts faster. that would be categorized as chemistry
Any metal which can get oxidised in the presence of oxygen from the air and water.
What is the difference in weight between a 350 Chevy and 496 Chevy?
The most obvious diff is 350 CUBIC inches is much small that 496 cubic inches. Also likely the 350 is a small block where as the 496 is a big block. The 496 will be a physically appearing bigger motor if that is the case. With great displacement also comes greater power or power potential. A mildly modified 350 can produce more power than a stock 496. Big Block Chev weighs in at around 675 Pounds and a 350 small block weighs in at about 575 pounds.
I
would assume scince is wood you could recycle it some way

Why do golf balls of the same brand have different bounce heights?
Answer by FutureLPGAgolfer
This may sound a bit confusing but I'll try my best to explain. For example, there is about six types of Titelist (sorry for spelling if it's wrong). SO, there is DT Solo, NXT, Pro V1, etc. DT Solo is a soft ball and soft balls have more backspin. Pro V1X is a hard ball which means, once it bounce... it keeps on going. Your wondering how they do that. Inside the golf ball they put different chemicals and different types of material so all those Titelists arn't the same at all just because of what is inside of them. It doesn't matter if it's the same brand because they are all different inside. The white plastic thing around the ball isn't the same either.
What effect does heat have on volume of air?
Heating a gas increases its' volume if the pressure remains constant. Heating a gas with the volume consant increases the pressure. See the Related Question linked to the the left of this answer: = How do you solve an Ideal Gas Law problem? =
What are examples of metabolic waste?
Urine and sweat are examples of metabolic wastes. Feaces are NOT metabolic wastes.
Is it possible to light a candle using mirrors and sunlight?
Possibly. The mirrors would have to be used to reflect the light onto a small space. A better way would be to use a magnifying glass; I remember doing this when I was younger.
How long does it take for a wool jumper to decompose?
Your answer depends on where you put the jumper for the purpose of decomposiiton.
On its own in extremely cold air with low humidity, the process may take decades. In a damp landfull smothered in foodwaste and yardwaste, the process would take much less time.
