What's the difference between Fahrenheit and Celsius?? (Weather homework question)?
Ok, I have a project to do on and the question is," What's the difference between ferenheight and celcius?" It's for biogrophy class. I am in 6th Grade. Please help me because me and my two friends both need help with that class project and we're in the same class so it's gonna be harder than I thought it would be. Please help and leave as much information and weather websites as possible for me and my two friends for the biogrophy class project. Thank you!!
Does Charles Law show that at the absolute zero temperature volume of a gas becomes zero?
Yes. For a hypothetical “ideal gas” the volume at absolute zero is also zero. This is because the molecules of which the ideal gas is composed have zero volume.At ordinary temperatures and pressures, the volume of molecules is negligible so Charles’s Law works fine. However, working at high pressures in particular there are modified versions which allow for the volume of the molecules.The hypothetical ideal gas does not (of course) condense to a liquid, which real gases do because of interactions which are not accounted for in Charles’s Law.
How many grains of sand are there in a 3 minute sand timer?
18936834, give or take a grain.
An aluminum sphere is 8.35 cm in diameter.?
Change in volume = (Coefficient of volume expansion) x (Original volume) x (Change in temperature) Original volume = 4/3(pi)(r)^3 where r= 4.175cm, and this would make V= 304.8 cm^3. For aluminum, the coefficient of volume expansion is 75x10^-6 /degC. (This is three times the coefficent of linear expansion). The change in temperature is 200-30 = 170 degC. Plugging it in, Change in volume = (75x10^-6 /degC) x (304.8 cm^3) x (170 degC) Change in volume = 3.887 cm^3. Hope this helps, and I hope all my math is right. :)
