Why is it possible to boil water in a thin paper container but not in a cardboard container?

User Avatar

Asked by Wiki User

Thin paper containers can withstand the heat of boiling water because they have minimal insulation and can transfer heat effectively. Cardboard containers, on the other hand, have thicker layers and more insulation, which makes it difficult for the heat to transfer efficiently, resulting in the cardboard being unable to withstand the heat and potentially catching fire.

What is inside one of the open spaces of an ice crystal?

User Avatar

Asked by Wiki User

Inside one of the open spaces of an ice crystal, there are water molecules arranged in a lattice structure. These spaces are called "interstices" and they allow for the formation of a repeating pattern of hydrogen bonds between adjacent water molecules. The arrangement of the water molecules determines the shape and symmetry of the ice crystal.

What is meant by 1 general multiplicity 2 chemical occupancy 3 site multiplicity 4 occupation number in crystallography?

User Avatar

Asked by Pranavbardapurkar

  1. In crystallography, "general multiplicity" refers to the number of symmetry operations (such as rotations or reflections) that can be applied to a crystal lattice to generate equivalent positions.
  2. "Chemical occupancy" refers to the number of atoms occupying a specific position in the crystal lattice. It indicates the stoichiometry (ratio of different atoms) within the crystal structure.
  3. "Site multiplicity" refers to the number of equivalent sites (positions) within a crystal lattice that are indistinguishable based on the crystal's symmetry elements.
  4. "Occupation number" refers to the number of atoms or molecules occupying a specific site in the crystal lattice. It indicates if the site is fully occupied (1.0), partially occupied (less than 1.0), or vacant (0.0).

Name and describe the state changes in which solids and liquids become gases.?

User Avatar

Asked by Wiki User

The state change in which a solid becomes a gas is called sublimation. This occurs when a solid substance directly transitions into a gas without passing through the liquid phase. The state change in which a liquid becomes a gas is called evaporation or vaporization. This occurs when a liquid substance turns into a gas by absorbing heat energy.

Why liquids are less common than other two states of matter on earth?

User Avatar

Asked by Wiki User

Liquids are less common than solids and gases on Earth because of the specific conditions required for them to exist. Liquids require a specific range of temperature and pressure to be present. Additionally, liquids can easily change into gases due to the mobility and energy of their particles, which further decreases their prevalence compared to solids and gases.

Is flower a liquid or a solid?

User Avatar

Asked by Wiki User

A flower is neither a liquid nor a solid. It is a plant organ that consists of various parts, including petals, sepals, stamens, and pistils. It is considered a solid object.

Example to demonstrate friction?

User Avatar

Asked by Wiki User

Yes, cars have less friction when they roll on the ground than when the breaks are on (sliding). That's why breaks stop the car, because the sliding friction of rubber on asphalt is very high.

Why does not the temperature change during change of state from solid to liquid?

User Avatar

Asked by Wiki User

Addition of heat produces more liquid, breaking apart the intermolecular bonds, rather than increasing bond oscillation (increasing temperature).

Is vapor a liquid a solid or a gas?

User Avatar

Asked by Wiki User

Water (H2O) comes in three different physical states; liquid, solid and gas. Water vapor is water in a gaseous state. Water vapor can be produced from the evaporation or boiling of liquid water or through the sublimation of ice. Typically water vapor is constantly being created by evaporation. Unlike the solid or liquid state of water, water vapor is not visible to the human eye.

Is carbon gas solid liquid?

Carbon is a solid at room temperature.

What is characteristics of solid matter?

User Avatar

Asked by Wiki User

It has a definite volume and shape and cannot be compressed.

More information:

There are three types of matter, gas, liquid and solid. Gas matter have no definite volume, no definite shape and can be compressed. Liquid matter has a definite volume, no definite shape and cannot be compressed. Solid matter has a definite volume, a definite shape and cannot be compressed.

This is in the 'Cycles' Science subject, learnt normally at Primary/Grade 3/4 in Primary/Elementary schools.

Detailed information:

Gas:

Gas particles are very far apart from each other, mainly the reason why they can move freely everywhere.

Liquid:

Liquid particles are next to each other, they slide past each other, however, they cannot move freely, unlike gas particles.

Solid:

Solid particles are the most arranged particles of all. They can only shake a little in their current position, and cannot move around at all.

I hope this information will be helpful to you!!!:)

P.S. I am just a primary 5 student, eleven years old studying in a Singapore top primary school. My answer may not be very accurate, but all the same I hope it will help you/your child in his/her studies.

Is gak a solid or liquid and why?

User Avatar

Asked by Wiki User

Gak is a liquid and solid. In the school science lab ,I did an experiment and made gak out of borax, water, saturated water, Elmer's White glue, and food coloring.If you mush it feels like liquid and if you leave it somewhere it will look like it is frozen and it will look like it is a solid.

What is the breakdown voltage of PN junction diode?

User Avatar

Asked by Wiki User

A Zener diode doesn't allow almost any current to flow below a certain voltage. Above this voltage (the breakdown voltage), the amount of current that can flow is almost unlimited; meaning that the device acts as an "open" for lower voltages, and as a "short" for higher voltages.

Why transistor cannot be used as rectifier?

User Avatar

Asked by Vidyan

By connecting collector to base, you get a *lower* forward voltage drop than with a simple diode.

Example: germanium diode-connected transistor has a drop of about 0.13 volts, rectifier diode about 0.3 (over 2.5 times)

It's just that rectifiers are optimised for rectification, are designed to work at (generally) higher currents, and are cheaper.

What is matter with slow moving particles?

User Avatar

Asked by Wiki User

Please clarify what you mean by slow-moving air. Do you mean an air mass that is moving slowly, or a gas particle that is moving slowly?

If you mean the latter, perhaps this answers your question: for a given temperature, gas particles with less mass move faster than gas particles with greater mass. Additionally, for a given species, a lower temperature corresponds to lower particle velocity, with absolute zero corresponding to no movement whatsoever.

The process of a solid changing directly to a vapor without forming a liquid?

User Avatar

Asked by Wiki User

a solid can change directly into a vapor if it is super heated very fast so fast that the solid does not have time to turn into a liquid

Can you liquefy oxygen at -183 Celsius?

User Avatar

Asked by Wiki User

At atmospheric pressure, yes. This is the melting point of oxygen at one ATM. The process is usually done as follows:

1) Air is filtered and put into a chamber.

2) It is then compressed. Pressure rises, so temperature increases. The pressurized gas chamber gives off some of its heat.

3) Then the reverse happens- the gas is expanded quickly. The resulting release in pressure makes the temperature go down.

4) One cycle is not enough. The cold air at the end of the cycle is used to cool down air coming in in step one. This means that the incoming air is colder to begin with, so the whole process gets closer.

How many miles does light travel in 100 seconds?

User Avatar

Asked by Wiki User

The speed of light in a vacuum is 186282.397 miles per second.

The distance something travels in a given time and at constant speed is given by

d = s*t

where d is the distance traveled, s is the speed, and t is the time.

In our case, s = 186282.397 miles per second and t= 100 seconds.

d = (186282.397 miles per second)*(100 seconds) = 18628239.7 miles

So, in 100 seconds, light travels 18628239.7 miles.

Why are npn transistors used more often than pnp transistors?

User Avatar

Asked by Wiki User

The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
