The COP usually exceeds 1, especially in heat pumps, because instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required. Most air conditioners have a COP of 3.5 to 5. [3]
Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020.
An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone.

Condensation forming in the low pressure zone above the wing of an aircraft due to adiabatic expansion. Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
[4] With highly activated phenols such as resorcinol, the reaction can be performed under much milder conditions. This provides a useful route to umbelliferone derivatives: The Pechmann condensation as applied to 7-hydroxy-4-methylcoumarin. For coumarins unsubstituted at the 4-position, the method requires the use of formylacetic acid or ester.
Usually, DNA condensation is defined as "the collapse of extended DNA chains into compact, orderly particles containing only one or a few molecules". [3] This definition applies to many situations in vitro and is also close to the definition of DNA condensation in bacteria as "adoption of relatively concentrated, compact state occupying a ...
[3] Considering the phrase " American Dream ," the image that tends to come to mind is a successful, self-made American individual who has worked hard in order to obtain a life of financial security, with occasional luxury and minimal privilege, even if the sociological reality varies widely by region, class, place, and time.
