Can you explain why you feel warm when you are standing away from a campfire?

A fire burns fuel to produce heat and gasses. Some of the heat comes off as visible light and some warms the air in and around the fire and this rises with the smoke.
However, allot of the heat comes off as infra red radiation - a form of light that you can not see with your eyes, but that you can feel with your skin (as the warmth from the fire).
Your skin is always trading heat with its surroundings, your body is always losing heat at a moderate rate to the air touching it. When more heat comes in than goes out, the skin feels warm. So the side of you that faces a fire will feel hot because it is getting more heat than it is losing (because it is absorbing the infra red radiation), while your back surface is shaded from the fire's energy (by your front) and this will be losing more heat than it is receiving and will therefore feel cold.

∙ 12y agoyou feel hot because, when you stand near a fire the temperature around you is gretter than your body temperature leading to an exchange of heat, your body then gain heat from the fire i.e an endothermic reaction occurs and the heat absorbs leads to an increase in your body temperature making you to feel hot!

∙ 14y agoStanding near the campfire raises the temperature of your body, but this goes mostly unnoticed as it raises the temperature of the air around you as well. When you stand away from the campfire the air around you is colder than it was next to the fire, therefore the difference between your body's temperature and the air is more noticeable.

If you were standing on the epicenter of an earthquake when would you feel the vibrations in relation to someone else standing 50 miles away?
The epicenter is directly above the focus, or starting point, of the earthquake. Anyone standing there would be the first to feel the vibrations.Seismic waves can vary from a low speed of 2 to 8 kilometers per second in the earth's crust to as much as 13 kilometers per second in the deep mantle. Some waves that go downward and reflect up off the earth's core may actually arrive before the waves that go in a straight line!A rough approximation says that someone 50 miles away would feel the vibrations between 6 and 40 seconds later.A+ls: before the other person

Why is it when it's raining the water in the swimming pool is warm but when it is sunny the water in the swimming pool is cold?
It's all about how your body reacts to relative temperatures. The truth is that the pool temperature is not likely to be the culprit. It's more about how your body perceives the difference between the outside temperature vs the pool temperature. The transition from standing in the hot sun to getting into your pool makes the water feel colder than it might feel than if you are standing in cold rain before entering the pool.
