Problem: Article: You want to work with clean skin, so remove any makeup or other products that may be on your face. Gently pat the skin dry, taking care not to irritate it by rubbing with a towel. Comedones are easier to remove when your pores are nice and wide. A little steam facial will not only open your pores up to prepare for extraction, but it will also put you in a nice, relaxed mood! While you’re waiting for the water to boil, find a towel you can drape over your head during the steaming process. The towel will trap the steam and keep it from escaping, improving the effects of your steam facial. When the boiling water is producing enough steam, remove it from its heat source. Lower your face over the bowl, letting the towel drape over you like a tent, trapping the steam. Stay in this position for 4 to 8 minutes.   Be careful when handling the hot water container. You may wish to use oven mitts to protect your hands. Do not bring your face close enough to the steam to burn your skin. The effect of the steam should be pleasant, not strident. A little bit of redness from the steam is normal, but stop the steam facial if your skin begins to feel irritated.
Summary: Wash your face. Bring water to a boil over a stove. Place a towel over your head. Bring your face close to the steam.

Problem: Article: Following the vet's instructions, treat your cat's ear mites to eliminate the problem.  Never treat ear mites without having them diagnosed by a vet. Anti-mite solutions could easily irritate or worsen problems with similar symptoms to ear mites.. Regular and thorough ear-cleaning is required to cure ear mites. Commercial cleaner is usually used to clear the ear of debris, followed by cleaning with prescription ointments.  A cat's tail should be cleaned as well, as they frequently wrap themselves in their tails to sleep. This means eggs and mites can spread to the surrounding fur.  Ointments and pesticides prescribed by your doctor should be used for 7 to 10 days following an outbreak. If you have any other pets in your home, clean their ears as well as ear mites have likely spread.  Cats can be stubborn about taking medication. Have a friend help you if your cat is particularly resistant to treatment. Try to limit your cat's interactions with places and situations that expose him to ear mites.  If you have an outdoor cat, you might consider keeping him inside if he is prone to frequent ear mite outbreaks. However, outdoor cats can be difficult to keep inside if they're accustom to coming and going as they please. If your cat suffers from Feline Immunodeficiency Virus (FIV) he should not go outside. Not only does his weakened immune system make him more susceptible to ear mites, the spread of FIV can be prevented by limiting his exposure to strange cats. Be wary of animal shelters and pet stores where ear mite outbreaks are common. Check all incoming kittens and cats for signs of ear mites before releasing them into your home. Items cats use frequently should be washed after an outbreak.
Summary: Treat your cat's ear mites. Avoid past mistakes. Wash a cat's bedding and toys.

Problem: Article: To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature. Then divide this number by the fraction 5/9. The formula should look like this:  C=59∗(F−32){\displaystyle C={\frac {5}{9}}*(F-32)}  (C){\displaystyle (C)} = Celsius temperature and (F){\displaystyle (F)} = Fahrenheit temperature For example, if the temperature is 100°F, you would first subtract 32 from 100, which would give you 68. Then, you would multiply 68 by 5/9, which would give you the temperature of 37.778°C. If you live outside the United States and use the Celsius scale, you can, of course, skip this step. You can also use online temperature converters to simplify this step. After converting the air temperature to Celsius, you need to find out the saturated vapor pressure, or the maximum amount of water vapor the air at that temperature can hold. You can use this formula to calculate the saturated vapor pressure:  es=6.11∗10(7.5∗T237.3+T){\displaystyle e_{s}=6.11*10({\frac {7.5*T}{237.3+T}})}  (es){\displaystyle (e_{s})} = standard vapor pressure and (T){\displaystyle (T)} = air temperature You can use the same formula to find the actual vapor pressure. All you have to do is substitute the dew point for the air temperature in the formula.  e=6.11∗10(7.5∗Td237.3+Td){\displaystyle e=6.11*10({\frac {7.5*Td}{237.3+Td}})}  (e){\displaystyle (e)} = actual vapor pressure and (Td){\displaystyle (Td)} = dew point You can find the dew point by checking the weather page of your local newspaper or a website that publishes weather information for your local area, such as weather.gov. Now that you have the saturated vapor pressure and the actual vapor pressure, you can find the relative humidity. Just divide the actual vapor pressure by the saturated vapor pressure and multiply that number by 100. You can use this equation:  rh=ees∗100{\displaystyle rh={\frac {e}{e_{s}}}*100}  (rh){\displaystyle (rh)} = relative humidity, (e){\displaystyle (e)} = actual vapor pressure, and (es){\displaystyle (e_{s})} = standard vapor pressure. If math is not your forte, there are several online calculators you can use to calculate relative humidity. Just punch in the temperature and dew point, and you can find out what the relative humidity is in a fraction of a second. The National Weather Service’s relative humidity calculator is one you can use: https://www.wpc.ncep.noaa.gov/html/dewrh.shtml
Summary:
Convert the air temperature and dew-point temperature to Celsius. Calculate the saturated vapor pressure with a formula. Find the actual vapor pressure with the same formula. Calculate the relative humidity. Use an online relative humidity calculator for speed and convenience.
