How is piloerection related to heat loss?
Piloerection, or goosebumps, is a physiological response where hair stands up on end. In response to cold temperatures, piloerection traps a layer of air near the skin to provide insulation and reduce heat loss. However, in response to heat, piloerection is not as effective in reducing heat loss.
Why does concrete floor feel cold when you touch it?
Concrete is a good conductor of heat, which means it can quickly absorb and transfer heat away from your body when you touch it. This rapid transfer of heat can make the concrete feel cold to the touch, even if the actual temperature of the concrete is the same as the surrounding air.
Why did you fell heat from the flame even if you did not touch it?
You are able to feel heat from a flame even if you do not touch it because heat travels through the air via radiation. When a flame is present, it emits infrared radiation that can be felt by your skin as warmth.

Does a solar cover have to actually touch the water?
Yes, the solar cover should touch the pool water. The cover absorbs the heat from the sun and then transfers that heat to the water. If the cover does not touch the water, most of the heat will end up in the air between the cover and the water rather than going into the water itself. Hope this helps ...
What are plants that never touch the groungcalled Give two examples.?
Plants that never touch the ground are called epiphytes. They grow on other plants, typically trees, and derive moisture and nutrients from the air and surrounding environment. Two examples of epiphytes are orchids and bromeliads. These plants often have specialized adaptations to thrive in their aerial habitats.
Which insulation holds the heat the best?
Glass traps solar heat. Greenhouses are made of glass so they absorb heat for the plants.
Which human response is most likely to occur because the air temperature is 90f?
The most likely human response to an air temperature of 90°F is to feel hot and sweaty, seek shade or air conditioning, and stay hydrated to prevent overheating or heat-related illnesses.
What rises quickly?
Hot air rises quickly due to its lower density compared to the surrounding cooler air. Additionally, prices can also rise quickly in response to demand or market conditions.
Why power electronic device symbols are not circled?
Because the power electronics devices can not be packed, they should always be in touch with air for heat release.
How Scrubbing Tower Work?
An air cooled heat exchanger works by forcing a heated fluid through tubes that have fans blowing air over them to cool them externally. Usually, the tubes have fins attached to them to increase the surface area in contact with the air. By facilitating more efficient heat transfer, this increases the heat exchanger's efficiency. After the heated fluid cools down and returns to the system, it releases its heat into the air. In petrochemical plants, oil refineries, power plants, and other industrial settings, this method is especially helpful for cooling process fluids and gases
Engine hot to the touch?
Every vehicle gets hot to the touch, it doesnt mean that your over heating or anything... a Plymouth Voyager gets 195 Degrees. the heat is actually better for the invironment then when the engine is cold because the heat helps burn all gases and keeps it from the air.
