Unfortunately, though, it could be something more. Did someone say fever? To protect others, do not go to places like a GP surgery, pharmacy or hospital. Stay at home.

Children under 5 For advice about taking a temperature in a child under 5, see how to take a baby's or young child's temperature.
Information: You can also use a digital thermometer in your armpit. But, nobody's perfect, and sometimes you're left without the one thing you need most.
Luckily, you can learn how to tell if you have a fever even if you don't have a thermometer on your nightstand. Figuring out whether you have a fever in the first case can be tricky, but it's really important. Knowing your temperature can indicate whether or not you need to go to the emergency room. Even if it's a low temperature, knowing what's going on with your body is the first step towards feeling better. If you have a doctor's appointment scheduled for the next day, keeping an eye on your symptoms will help your GP better take care of you.
And even if you don't have a thermometer, learning these indicators can be another step towards getting well. When you think you're running a fever , you'll probably ask someone to feel your forehead.
That's not too far off, experts say. Do not use the palm, as it is not as sensitive to temperature changes as the back of the hand is.
Beverly Hills concierge medicine physician Dr. Ehsan Ali , M. It's easier if you can get a friend, roommate, or family member to check your forehead, but you can try yourself, too. There's no outdoor life without risk-taking.
Good suggestion. It works better if the straw is sufficiently narrow to allow the liquid to rise part way up through capillary action. Escoce Escoce 4, 11 11 silver badges 21 21 bronze badges. Your "subzero" statement lacks a unit, do you mean Fahrenheit? Thowing hot water down might, depending on quantity and height. Hot water will cool faster higher rate of change of temperature , but it will not freeze faster than, or even overtake the temperature of, the cold water.
At best, the hot water temp will approach the cold water temp and will asymptotically get closer and closer, never passing it. This is assuming all other factors are equal. Aaron True, but the assumption all other factors are equal does not hold. My observation is entirely empirical. One possible construction of a thermometer would rely on refraction of light in different media: When light enters a more dense substance higher refractive index , it 'bends' more towards the normal line.
Hot water is less dense than cold water. Calibrate the thermometer based on the angles of refraction of a straight object with different known temperatures of water eg. Other constructions would rely on expansion of some fluid: For closed housings, the expansion would indicate temperature eg.
In case of a gas in an open tube, the escaping gas with higher temperature would deflect an obstruction eg. If the obstruction at the opening is attached to a fixed joint allowing centrifugal movement, then the rate of spin would indicate temperature, like car engines, or paddle wheel boats, speedometers.

The calibrations methods provide approximate temperatures at sea level. The crux of the answer was ways to build your own thermometer without a lab apparatus. Sign up or log in Sign up using Google.
