The heat can be transferred to the surrounding air using radiators, hot water coils (hydro air), or other heat exchangers.

A rising body of fluid typically loses heat because it encounters a cold surface.

Bulk motion of fluid enhances heat transfer in many physical situations, such as (for example) between a solid surface and the fluid.

Topics covered by experiments performed included soil mechanics, meteoroids, seismology, heat flow, lunar ranging, magnetic fields, and solar wind.

These waves travel upward and dissipate in the corona, depositing their energy in the ambient matter in the form of heat.

On one hand, it was clear that viscous stresses would eventually cause the matter towards the center to heat up and radiate away some of its gravitational energy.

She cools his domain with Spring air, venting heat up to the surface, creating summer.

The heat flux density is the amount of energy that flows through a unit area per unit time.

Without this heat retention effect, the average surface would be 18 C, in contrast to the current 15 C, and life would likely not exist.

Elephants have difficulty releasing heat through the skin because of their low surface area to volume ratio, which is many times smaller than that of a human.

And he showed that gasses such as CO2 absorb heat, thus acting like a blanket warming Earth's surface.

Another hypothesis is that some form of barrier exists in Uranus's upper layers that prevents the core's heat from reaching the surface.

Extraterrestrial occurrences Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface.

On Venus, a global resurfacing event may have shut down plate tectonics and led to a reduced heat flux through the crust.

Possible mechanisms for the vapor release are sublimation from about 0.6 km2 of exposed surface ice, or cryovolcanic eruptions resulting from radiogenic internal heat or from pressurization of a subsurface ocean due to growth of an overlying layer of ice.

With heat from the bottom and heat from the top.

Raising its wings and exposing the undersides increases the exposure of its body surface to the air by 16 , facilitating further heat loss.

The tetrafluoroethylene in the container had polymerized into polytetrafluoroethylene, a waxy solid with amazing properties such as resistance to corrosion, low surface friction, and high heat resistance.

I am hot.

I'm hot.

Is it hot?

A lot of heating, frictional heating. It's going 18 thousand miles an hour.

It's a hot day.

Once the material diffusively and radiatively cools just beneath the photospheric surface, its density increases, and it sinks to the base of the convection zone, where it picks up more heat from the top of the radiative zone and the convective cycle continues.

When a planet generates a significant amount of heat internally, such as is the case for Jupiter, convection in the atmosphere can transport thermal energy from the higher temperature interior up to the surface.

It was hot yesterday.

It was very hot.

We're hot.

It's hot in here.

It's hot in here.

Yesterday was hot.

I like the heat.

Was it hot yesterday?

It is hot today!

That's a heat engine.

Heat, cold and salt

Wind waves in the ocean are called ocean surface waves.

We punched a bunch of heat probes. Everything made sense, except, at the axis, there was missing heat. It was missing heat.
