Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

How does melting differ from freezing?

User Avatar

Asked by Wiki User

For any given substance the melting point and the freezing point are the SAME temperature.

However, if the substance is increasiung in heat to move from solid to liquid then it is the MELTING POINT.

If that same substance is losing heat to move from liquid to solid then it is the FREEZING POINT.

Similarly, when moving from liquid to gas ity is the boiling point

, and when moving from gas to liquid it is the condensing point.

What is a spiral notebook made out of?

User Avatar

Asked by Wiki User

Spiral notebooks typically consist of paper pages bound together with a metal or plastic spiral coil. The cover can vary in material, often made of cardboard, heavy paper, or plastic. The pages are commonly lined or blank, providing a versatile format for writing, drawing, or note-taking. Search FashionTIY in Google.

Is notebook paper translucent?

User Avatar

Asked by Wiki User

Notebook paper is generally not translucent. It is designed to be opaque, providing a solid writing surface for ease of readability and writing comfort. However, some specialized types of paper, such as tracing paper or vellum, are translucent and allow light to pass through, making them suitable for tracing or layering purposes.

Are tides high on every full moon or new moon?

User Avatar

Asked by Wiki User

There are two high tides and two low tides every day.

The tides follow the Moon's drag . So as the Earth rotates daily, that part facing the Moon has an high tide. The opposite of the Earth also has an high tide at the same time; this can be thought of as a 'WHEEL BALANCING'effect.

As the Moon orbits the Earth, the height of high tides and low tides varies.

At New/Full Moon we have Spring(very High) high /low tides . This is because the Sun and Moon are pulling together.

When the Moon is at first or last Quarter. The Sun and Moon are pulling at right angles to each other, so the Earth has Neap(not so high) high/low tides.

At the Vernal and Autumnal Equinoxes The Spring tides can be even higher/lower again . This is due to the Earth's nearness to the Sun, on its ellipsoidal orbit.

Since the Moon is moving/orbiting about the Earth, the mean time between High Tide and Low Tide is 6 hours 22 minutes and a few seconds. This means that over a 24 hours period (Midnight to midnight) you may 'miss' a tide. There will be only three tides in a given day ; 2 high and one low or, one high and two lows.

I would suggest that you have a look at the yearly tide tables/times for a given location, say New York City or better still the Bay of Fundy. Just compare the high/lows times for a given location.

Itbis quite a complex, but beautiful natural system.

Hope that helps!!!!!

Are rubber and glass when heated examples of crystalline solids?

User Avatar

Asked by Wiki User

Glass as a solid is acturally a 'super-cooled liquid'. If left for many years the glass will appear to go cloudy, light does not trasnmit . This is the glass forming a crystalline solid.

Glass is classified as a super-cooled liquid becasue it is a liquid below its melting point, but has not formed crystals, to become solid.

NB Under certain weather conditions, water can become super-cooled. That is it is below its freezing point but still remains a liquid.

What is the abbreviation for solid?

User Avatar

Asked by Wiki User

In a chemical equation it it '(s)'.

e.g.

2HCl(aq) + CaCO3(s) = CaCL2(aq) + H2O(l) + CO2(g)

(aq) = aqueous (water based solution).

(s) = solid

(l) = liquid

(g) = gas

How fast are you moving in space?

User Avatar

Asked by Wiki User

Tectonic plates travel at about 2 inches per year. Meaning since opening this page, on average, you've traveled: 2 nano meters per second

The Earth is spinning at about 1,000 mph at the equator. Meaning since you've opened this page you've traveled about: 1 mile per 3 seconds

The Earth is also traveling around the sun at 66,000 mph! So combined with the earth spinning you've traveled: abut 30 miles per second

Compared to neighboring stars, our sun is moving toward a local star called Vega at 43,000 mph! So that combined with the Earth spinning and the Earth traveling around the Sun you've traveled: about 50 miles per second

The sun is orbiting the Milky Way Galaxy at 483,000 mph! So that combined with the Earth spinning and the Earth traveling around the Sun you've actually traveled: about 250 miles per second

The Milky Way Galaxy is on a collision course with the Andromeda Galaxy at 225,000 mph! So you've actually traveled: about 400 miles per second

The entire Milky Way galaxy is moving at 1,300,000 mph! Combined with everything else, you have traveled: about 1000 miles per second

The Universe is expanding! Meaning from the vantage point of the furthest known Galaxy, you've traveled: about 300,000 miles per second

But speed is relative to yourself and you know how fast you are moving so how fast are you moving?

Occurs when a gas cools and changes into a liquid?

User Avatar

Asked by Wiki User

When gas cools and changes into liquid, it undergoes a process called condensation. This occurs when the temperature of the gas decreases, causing its particles to lose energy and come closer together, eventually forming liquid droplets.

What does revolution mean in space?

Asked by Wiki User

The revolution of a planet means a celestial body revolving around a star.

Ex: Earth revolves around the sun

While rotation is the spinning of a celestial body on its own axis which some people get confused about

Wells from which pressurized water flows to the surface are called?

User Avatar

Asked by Wiki User

Artesian Wells.

Water can be brought to the surface, natural air pressure, providing it is no deeper than 34 feet. (Air pressure allows for this).

Water any deeper than 34 feet, requires a pressure system to bring it to the surface.

What provides the energy for the earth?

User Avatar

Asked by Wiki User

Earth's surface energy budget is 99.96% from the Sun and 0.04% from heat conducted from geothermal activity.

Below the earth's surface, the energy allowed for the creation of magnetic field and seismic activity is from the heat and motion of the nuclear fission energy inside the core where most of heavier radioactive element is there.

Is carbonate in the periodic table?

User Avatar

Asked by Wiki User

Carbonate does NOT appear in the Periodic Table, because it is not an elementy, but an 'ANION'.

The carbonate anion has the formula of 'CO3^(2-)'.

That is the anion consists of one carbon and three oxygen atoms.

Both Carbion and Oxygen are elements and appear in the Periodiuc Table.

What two elements make iron?

User Avatar

Asked by Wiki User

Iron is an element in its own right. So there are no two elements that make iron.

However, Steel is an alloy of iron and carbon. Iron and Carbon are tweo different elements. So steel contains two different elements.
