Panting observed in overheated birds and mammals dissipates excess heat by?
Most terrestrial animals dissipate excess heat by evaporation. This is done by either sweating (like humans) or by panting (like dogs).
What does the word dissipate mean in reference to energy transfers?
It means for the energy to get away, to spread out. Usually used for excess heat.
How does the skin dissipate excess body heat?
Dissipatation of excess body heat results from capillaries being expaned in order to get more blood closer to the skin's surface. The body also makes sweat, which cools the body when it evaporates.
Need of CPU?
dissipate heat
What device typically uses heat spreaders to dissipate heat?
memory
Excess heat in rivers is caused by what pollution?
Thermal pollution causes a rise in the ambient water temperature in rivers. Excess heat often causes algal blooms and increased metabolism in aquatic animals. This results in a shorter life span for both the plants and animals.
Why is a heat-sink used on some equipment?
The main purpose of a heat sink is to dissipate excessive heat away from the device that it is attached to. Some small integrated circuit components are so physically small that an over excess of heat generated by themselves would destroy the device. The heat sink is placed on the IC to prevent this from happening.
Why do African Hunting Dogs have such large ears?
to dissipate heat.
What has numerous water and air passages to dissipate heat?
A Radiator.
How does radiation dissipate?
When the Sun's heat warms the ground and air.
Are small components typically made out of aluminum with fins that help to dissipate heat?
heat sinks
Do polar bears have large ears?
Polar bears, like most animals that live in cold regions, have small ears so they don't dissipate heat through them rapidly.
