Science Experiments

Yoga can be an independent variable in some experiments and a dependent variable in others.

Fresh water is probably the likely candidate. If you add salt to a liquid, its freezing point lowers. Meaning, it would need a lower temperature for it to freeze.

Yes... that is why solar power is a great resource in grasslands

No. Jupiter's atmosphere is mostly hydrogen, which is flammable, but since there is virtually no oxygen in Jupiter's atmosphere combustion is not possible.

A standardized variable in biology is a variable which is maintained as a constant in all aspects. They are maintained as fixed permits without any variations during experiments.

To extinguish an oxidising flame, you should remove the oxygen source by covering the flame with a non-flammable material like a fire blanket or using a fire extinguisher designed for oxidising fires. Never use water on an oxidising fire as it can make it worse.

Not necessarily. It may be one that the experimenter has no control over.

Heat water and allow steam to collect on an inclined surface. As it cools the condensation will form droplets and roll to the lowest edge where it can be collected as clean water. Debris, dirty particles are left in the boiling container.

Polyethylene

Polypropylene

Polystyrene

Poly(vinyl chloride) - (PVC)

Polytetrafluoroethylene - (Teflon)

Poly(methyl methacrylate) - (Lucite, Plexiglas)

Polyacrylonitrile - (Acrilan, Orlon, Creslan)

Poly(vinyl acetate) - (PVA)

Natural rubber

Polychlorprene - (neoprene rubber)

Styrene butadiene rubber - (SBR)

Polyamides - (nylon)

Polyesters - (Dacron, Mylar, Fortrel)

Polyesters - (Glyptal resin)

Polyesters - (Casting resin)

Phenol-formaldehyde - (Bakelite)

Cellulose acetate - (cellulose is a polymer of glucose)

Silicones

Polyurethanes

a constent is a value that never changes. for example number 8. the number 8 is not going to change, it's just 8. a coefficent is a number that multiples a variable. for example: 3n, the number 3 is the coefficent and it always come in front of a variable(in this case the variable is n).

Hydrogen Sulfate

1. The Earth is larger than the Moon
2. The Earth has a satellite (the Moon is that satellite)
3. The Earth has a gaseous atmosphere

# Nuclear power (and weapons) which was (mainly) discovered by Einstein's E=mc2 , which was then elaborated on byu many other scientists. # Biological warfare, and the mass killings caused by poisons. (Poison existed before, but this made it much, miuch more potent)

# The advanced physics and mathematics research into factories which makes anything from canned beans to machione guns incredibly cheap and efficient, while maximising potential. (Again, it existed before, but this makes so much much easier, not only weapons, but human rights abuse in East Asia)

yup........

vaseline is a petroleum gel and it has low density than water. So the vaseline came up on the water when the temperature changes. after some days when the vasline complitly removed the nail become rest ok for more details:)9633977254

Because closed-loop recycling produces more recyclable materials.

The reason why it is important is because if you don't measure the experiment then there is no way you will find out your conclusion

The criterion "better" is not well defined. A coolant can cool faster, or to a lower temperature, or be more affordable or less toxic than another coolant, or more environmentally friendly. Freon is better than ammonia by some criteria, and worse by others (it is less toxic, but more environmentally harmful). Liquid nitrogen cools things faster and to a lower temperature than ice does, but you might not want to put it in your drink (which would immediately freeze and become undrinkable). Water frozen into ice is a perfect coolant for some purposes, such as keeping my glass of ice tea cold. I would use no other coolant for that purpose.

The answer depends on what the experiment is trying to establish.

In 1773, Joseph Louis Lagrange introduced the component form of both the dot and cross products in order to study the tetrahedron in three dimensions

With any of the common GPS based performance meters or one of the many "dyno" or "speedometer" type applications available for most smart phones.

The largest spacecraft is currently the International Space Station, a permanently-occupied space habitat orbiting the Earth.

The largest rockets were the Energia series for the USSR (Russia) and NASA's Saturn V that launched men to to moon from 1969 to 1972.

The NASA "Ares V" heavy-lift rocket will launch lunar missions beginning in 2014.

Time is the independent variable.
