Do air conditioners help clean up indoor air pollution?
Air-conditioning systems might work excellent in keeping your home cool but fails to make your home pollutant-free. There are air-conditioners with Hepa filter or air purifiers but contains a potential health risk. Here are few facts associated with health risks with air-conditioners.• An uncleaned air-conditioner circulates more allergens in the air that you breathe indoor while adding to your illness.• An air-conditioner accumulates mold as it contains moisture, if left uncleaned then it might trigger serious COPD (Chronic Obstructive Pulmonary Disorder) for your family members.• Air-conditioners clean various indoor allergens, dust, and pollen from the air that you breathe. The cooling system pulls theses allergen inside and can again recirculate within no time.• The refrigerant gas leak from your air-conditioner can lead to creating toxic vapours while poising the air that you breathe indoor.• An air-borne disease such as Legionairre’s disease causes fatal infectious disease that produces high fever and pneumonia. Air-conditioners are associated to spread such infectious diseases.• The PM 2.5 is smaller particulate matters that go unnoticed by naked eyes. The air filters in an air-conditioner are inefficient to clean these smallest matters from the indoor air. This results in chronic asthma attacks, bronchitis and other breathing problems.Therefore, it is always safe and advisable to invest in an air purifier to clean the indoor air pollutants.
Its ok to leave a puppy under rain? (n2)?
Dont lose your minds fellas. Like in my earlier question! Ill never leave my dog under rain! THE THING IS WE CANT CONTROL RAIN.. so lets say it started raining suddenly! Will the puppy know to hide under a shelter fast! And yeah i keep my puppy outside in the morning! Isnt that better for him to play and run. Not just sitting or sleeping indoors. With weather like this. We re not able to tell if its gonna rain or not. Its not cold or warm
A wheel rotates with a constant acceleration of 2 rad/s^2. If the wheel starts from the rest, how many revolutions will it make in the first 10s?
Since the angular acceleration of the wheel is constant here therefore the equations of motion in terms of angular variables are applicable.The wheel would thus make 15.9 revolutions in first 10 seconds.
If you dropped a piece of ice at 0 °C into water of 0 °C, what would happen to ice?
Observations of a tour skaterNordic Tour skatingWater freezing to ice is a difficult process. If you look at a sea when the air temperature is below 0 the sea do not freeze instantly. The freezing always starts at an edge were water is connected to a solid state object. Some water molecules are than, by the random laws of quatum physics connecting to the existing ice which will make the ice grow outwards in the lake. The ice will grow until it covers the entire lake. The ice have than laid itself on the lake (is that an English expression?). The lake will appear as a safe place for walking, and it is, except at some points in the middle of the lake were the ice will be too thin to carry a man. Watch out!To avoid a cold bath you should not enter the ice directly after the ice have laid iiself over thr lake. What a few days. And heres comes the strange thing:Ice will freeze above 0 degrees.When the ice is all over the lake the ice will continue to grow even when the temperature is above 0. Actually it will not start smelting until the air temperature is above 5 degrees.The explanation must be that when the temperature is below 5 degrees water molecules are more likely to get stucked on ice rather than to get loose from ice. As energy is consumed when ice is melting and produced when ice is freezing, this means that a lake that is freezing do produce heat.The 0 degrees scenarioIn the suggested scenario the ice will grow and produce heat. The water close to the ice will be warm. Mayby up to 1 degree. The warm water will sink to the bottom. The water in the cup will then have a gradient with the warmest water in the bottom and a cover of ice.The final state will be an even cover of ice and and a somewhat warmer water in the bottom
