Cooling bath. A typical experimental setup for an aldol reaction. Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low ...
Freeze brand. Appearance. A feral horse (mustang) captured by the Bureau of Land Management and freeze branded using the alpha-angle system. From left to right the brand says the horse is registered to the federal government, was born in the year 2000 and carries the registration number 012790, indicating that it was branded at a BLM facility ...
Different species have different temperatures of their thermal neutral zones. In dogs, the thermoneutral zone ranges from 20–30 °C (68–86 °F). [9] In horses, the lower critical temperature is 5 °C while the upper critical temperature depends on the definition used. [10] Their thermoneutral zone is roughly 5–30 °C (41–86 °F). [11]
A degree day is a measure of heating or cooling. Total degree days from an appropriate starting date are used to plan the planting of crops and management of pests and pest control timing. Weekly or monthly degree-day figures may also be used within an energy monitoring and targeting scheme to monitor the heating and cooling costs of climate ...

Thermoregulation. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
With triple-digit temperatures forecasted, cooling centers will be open from Wednesday, June 5, through Friday, June 7. The first true heat wave of the summer is expected to hit the El Paso area ...
