Why do static electricity demonstrations work better on warm, dry days?

Question

I need some help for my science homework! I will really appreciate a SIMPLE answer! Thanks

Answer 1

On humid days, there is a lot of static electricity in the air, carried around by the water molecules in the air. (This is also the reason why lightning often happens when there is a storm). If it is also cold, then the water molecules are closer together, and any static electricity buildup is neutralized immeditely.

Wars, dry days mean little water vapor, so we have minimal dischrging and neutralization of charges. So experiments work better.

Answer 2

assume you magnify the construction of air
you will see air consists of so manu particls
some nitrogen,O2,CO2,other gases ,then some smoke
,dust prtcls,and -big AND- water particles(molecules)
so in case of wet air(lot of water) so electricity
passes gradually to things(walls,ground) so ions Don't
be collected to the amount that acts
But if the air is dry,so ions(static electricity) are collected
-can't be pass to environment-to a cartain level that
electricity shock appears
hope help

Answer 3

Humidity. When there is alot of moisture in the air it effectively absorbs the electrons that you are trying to get to show static.

Answer 4

Many folks ask approximately shocks skilled after they contact the door, submitting cupboard, raise, or different steel item. Static electrical power is generated at any time when 2 ingredients are in touch with every different. All ingredients are made from electric expenditures within the fabric atoms. In the universe there are identical quantities of poor electric cost (electrons) and constructive cost (protons). These normally attempt to keep in stability of identical quantities at each place. However, whilst 2 ingredients are in touch, one of the expenditures redistribute by means of relocating from one fabric to the opposite. This leaves an way over constructive cost on one fabric, and an identical poor cost at the different. When the ingredients transfer aside, every takes it is cost with it. One fabric turns into charged undoubtedly, and the opposite negatively. If the ingredients are equipped to habits electrical power away the expenditures will burn up and finally recombine. In this situation, static electrical power results could also be too small to be spotted. However, if the expenditures are separated quicker than the fabric can burn up them, the quantity of electrostatic cost builds up. Eventually a prime voltage, and the results of static electrical power, could also be spotted. Most trendy sneakers have incredibly insulating rubber or plastic soles. As you stroll, static expenditures can construct up at the soles of the sneakers. This is peculiarly real if the ground may be insulating. Some older nylon carpets are specially well at producing static electrical power. The cost at the sneakers soles induces static electric cost for your frame, and this cost looks as a prime voltage. Under extreme stipulations, greater than 15,000 Volts had been recorded. It is particularly average to revel in five,000V. In reality, many folks don't think a surprise from a static electrical power discharge lower than approximately two,000-four,000V. If you're interior, the factor may also be proved by means of strolling round for a even as without a sneakers on - you're going to most often no longer revel in surprise. When you sit down in a chair the touch among your garments and the chair can generate plenty of electrostatic cost for your garments. While you keep in touch with the chair your frame voltage remains low. If you lean ahead so that you again movements clear of the chair again, or if you happen to rise up out of the chair, then you're taking the electrostatic cost with you. Your frame voltage can upward push very swiftly to a prime voltage because the cost is separated from it is counter cost at the chair. Unfortunately remedy isn't regularly handy. Indoors, you'll check out elevating the air humidity to forty-50% rh with a humidifier. (You can verify the humidity with a low-cost humidity meter from a gardening keep.) Also, seem for sneakers with leather-based soles. In the electronics enterprise, and in locations in which electrostatic sparks would motive a hearth chance, folks most of the time put on in particular designed static dissipative sneakers to scale down electrostatic cost construct-up at the frame. It is much less most probably that issues can be skilled with non-polymer flooring, comparable to cement or wooden (despite the fact that varnishes can motive issues). However, exchanging the ground may also be high-priced! It is feasible to regard a few flooring with static dissipative therapies - however the improvement of this will likely most often put on off after a even as.

Answer 5

0% or very low humidity.
