Why are you more likely to see a mirage on a hot day than on a mild day?
The density of air increases as the air gets cooler. The greater the difference in densities is, the more the light refracted.
Explain the following statement you feel cooler on a hot day when you turn on a fan even though the air being blown around is hot?
Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.
Why is it more comfortable to exercise on a day when the relative humidity?
I assume you meant to say "is low" at the end of your question. In order to answer this. I need to explain a couple things. As humans, we sweat to cool down. The way this works, is as the sweat evaporates off our skin, it draws heat away from the body. In high humidity, evaporation is slower, and therefore we cool down more slowly. (in warm temperatures) So in low humidity, our bodies are better able to regulate excess heat, and keep us cooler. Also, humid air is harder for our lungs to process oxygen out of, so we get less oxygen with each breath in higher humidity.

Why doe a desert cooler cool better on a hot dry day?
hummm i dont really know i think it is food
Why does a wind from the ocean cool you on a hot summer day?
Most of the time it is because the wind is bringing in cooler air from another country or part of the ocean
What causes a lake breeze?
Water is not easy to warm up, so during the day the water is cooler than the land. This causes the lake to cool the air above it. The cooler, denser air the sinks, and must spread out onto land when it reaches the surface.
Why is it cooler at the beach during the day?
Usually a beach has a breeze blowing in from the ocean. This movement of air can cool your skin and make the temperature seem less. I would think that the air is still in the morning and as the sun heats up the air and land, this results in movement of the air.
What effect does a large body of water on the daily temperature of the air around it?
On a warm day, water absorbs from its warmer environment, lowering the air tempurature. On a cool night, heat is transferred from the water to its cooler environment, raising the air tempurature.
Why does weather usually become cool and clear after a severe thunderstorm?
Weather becomes cool and clear after a thunderstorm because of the instability in the air along the "frontal boundary" between warm air and cooler air pushing in behind it. The reason it usually becomes cool after a thunderstorm is because after the storms have settled, the jet stream has pushed the warmer air further east and the cooler air has moved in its place. Thunderstorms contain updrafts and downdrafts. The downdrafts (caused by falling precipitation) drag cold air down from the top of the storm. When this air hits the ground it spreads out in all directions. The air from this downdraft moving in the direction of the storm is called a "gust front" and arrives just ahead of it and brings a nice cool breeze on a hot day.
Does a ball bounces better on a cool day?
no
How does wind get its power?
Wind happens when warm air meets cool air. The warmer air rises above the cooler air, as it is less dense, and the cooler air is pulled underneath the warm air, as it has left a vacuum. The air is then moving around at fairly high speeds, and this is wind. This is why there are often large, sudden temperature changes a day or two before a storm.
Why does a fan keep you cool on a hot day?
the air is cooled when a fan is turning the cold air keeps u cool
What happens during the day of the beach?
The water is cooler than the land and air sinks over the water
How to Cool Off With a Spot Cooler?
When whole house air conditioning is too expensive, or a room in the attic is too hot, a spot cooler can be the perfect solution. It is now possible to buy a spot cooler, which is simply a portable air conditioner. This spot cooler is much easier to use than a window air conditioner, and can be wheeled from one room to another without much effort. Since the spot cooler is on wheels it is very easy to move around. Even though it is much more convenient than a window air conditioner, a spot cooler is also powered by electricity. It pulls the hot air into the unit, cools it off, and then sends it back into the room. Not only does the spot cooler air condition a room, it also dehumidifies the room. If there is a room in a building that has no air conditioning at all, such as rooms that have computerized equipment, a spot cooler will take care of that room with no problem. Spot coolers are perfect for any room without a window. If someone is renting a house and there is no air conditioning, it is much cheaper to get a spot cooler for the main rooms than getting whole house air conditioning. It is also very nice to have a spot cooler in an apartment that has no air conditioning. A spot cooler will cost more than a window air conditioner, however, it is more energy efficient and the cooling costs will be lower. The spot cooler is wonderful for someone who is working in a specific area and only needs that area to be cool. Perhaps you need to work in the garage on a hot summer day. Garages aren’t cool, and the spot cooler will take care of that problem. Spot coolers are also used for emergency situations. If a business needs to conduct a temporary shut down for maintenance purposes, the spot coolers will keep the workers cool and comfortable while this shut down is in progress. A spot cooler can either be rented or purchased depending on how long you will need it. There are always good deals on websites to rent or own one of these coolers. There are also stores that will be able to accommodate you in this way.
