The work done in a process on vapor cycles is represented by length of h, so it can be measured directly, whereas in a T–s diagram it has to be computed using thermodynamic relationship between thermodynamic properties. [1] In an isobaric process, the pressure remains constant, so the heat interaction is the change in enthalpy. [2]
McDermitt Caldera is possibly the oldest of a sequence of calderas formed by the Yellowstone hotspot. [6] The caldera was preceded by a lava dome that had been built by volcanic eruptions of rhyolite starting about 19 million years ago. [3] [4] This lava dome collapsed into a caldera in an eruption between 16.37 and 16.41 million years ago. [6]
The term caldera was introduced into the geological vocabulary by the German geologist Leopold von Buch when he published his memoirs of his 1815 visit to the Canary Islands, [note 1] where he first saw the Las Cañadas caldera on Tenerife, with Mount Teide dominating the landscape, and then the Caldera de Taburiente on La Palma.

Example of a flow diagram of a nuclear submarine propulsion system. Flow diagram is a diagram representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for flowchart, [1] and sometimes as a counterpart of the flowchart.
Henry's Fork Caldera is the circular structure in the center of this image, with left part of Island Park Caldera. The Henry's Fork Caldera in eastern Idaho is a caldera located in an area known as Island Park, west of Yellowstone National Park. The caldera was formed by an eruption 1.3 million years ago of the Yellowstone hotspot.
Caldera lakes in contrast can be quite large and long-lasting. For instance, Lake Toba in Indonesia formed after its eruption around 75,000 years ago. At around 100 kilometres (62 mi) by 30 kilometres (19 mi) in extent and 505 metres (1,657 ft) deep at its deepest point, Lake Toba is the largest crater lake in the world.
A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
