What is the best conductor of electricity between air water wood and glass?
water is the best conductor of electricity, compare to air the atoms in water is more closely to each other and that makes water more conductive than air, glass can be conductor it depends on it composition but not as good as water and wood is not a conductor unless it's wet.
Why does Sound travel faster through air than through wood?
It doesn't, sound travels faster through wood. The more dense the material the better the sound carries. Because wood is more dense than a gas such as oxygen the sound travles faster through the wood.
Is wood and paper a good Insulator?
Wood is a moderate insulator, while paper is a poor insulator. Wood has natural air pockets that help trap heat, while paper is more porous and allows heat to pass through more easily.
Which of these would allow sound to travel fastest air wood or water?
Sound travels fastest in solids, so it would travel fastest in wood compared to air and water.
What is the best conductor of heat between air water wood and glass?
Air at sea level has a specific heat of 1.0035 kJ/(kg*K). Air at room temperature has a specific heat of 1.012 kJ/(kg*K) Water at room temperature has a specific heat of 4.184 kJ/(kg*K) Therefore, since it takes more energy to increase the temperature of one kilogram of water (because it has a higher specific heat), water is a better insulator. This explains (roughly, though it is much more complex when taking in actual mass, size, and radiation) why on a hot day the air temperature will change much more than the temperature of a pool of water.
How much more dense wood than air?
more
What does a humidifier change?
It makes the air less dence it takes the water out of the air
Is wood a better insulator than glass?
No. Wood has more air in it than glass, and air is pretty much accepted to be one of the best insulators ever.
How much more dense is wood than air?
Wood is about 700 times denser than air. On average, wood has a density of around 700 kg/m^3, while air has a density of about 1.2 kg/m^3 at room temperature and pressure.
Is the air on a mountain top heavier?
no as you go higher the air gets less dence that's why it gets harder to breath.
Why does your 1992 golf gti lose power when warm?
all engines will loose power when warm because cold air is more dence than hot air and thus more explosive per cubic cm. this is made more obvious by turbo cars as the air is compressed aswell. try running a cold air intake through the grill.
Why a ball of steel sinks but boat made of steel floats?
The steel boat has more bouyancy because it is mostley filled with air as with the steel ball it is dence and heavy so it sinks
Is warm air less dence than cold air?
Yes, warm air is less dense than cold air. As air warms up, its molecules gain energy and spread out, decreasing the air's density. Conversely, cold air molecules lose energy and clump together more closely, making cold air denser.
What is the best conductor of electricity between air water wood and glass?
water is the best conductor of electricity, compare to air the atoms in water is more closely to each other and that makes water more conductive than air, glass can be conductor it depends on it composition but not as good as water and wood is not a conductor unless it's wet.
Why do wood shavings insulate better than solid wood?
Wood shavings have more air pockets between the individual pieces, creating greater insulation by reducing heat transfer. These air pockets act as barriers to heat flow, making the overall material more insulating than solid wood, which has fewer air pockets.
Is kiln dried wood better than air dried wood for woodworking projects?
Kiln dried wood is generally better than air dried wood for woodworking projects because it is more stable and less likely to warp or shrink.
What is mean that wood is a material hygroscopic?
a material is hygroscopic if it tends to pick up water from the air. Wood tends to pick up and give off water to the air. Different kinds of wood will pick up more or less. Every kind of wood has a balance point where it will not pick up more water. This point depends on the temperature and relative humidity of the air. The more moist the air, the more the wood will pick up, up to a point.
