The new iPhone 6 and 6 Plus each have a sensor that gives readings for barometric pressure. Barograph (free), displays real-time pressure data from that sensor. Weather watchers will know dropping ...
Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...
A room-temperature superconductor is a hypothetical material capable of displaying superconductivity above 0 °C (273 K; 32 °F), operating temperatures which are commonly encountered in everyday settings.
In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is expanding; typically caused by the pressure loss from flow through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment.
A digital thermometer reading an ambient temperature of 36.4°C (97°F) in an unventilated room during a heat wave; a high indoor temperature can cause heat exhaustion or heat stroke in a person. The World Health Organization in 1987 found that comfortable indoor temperatures of 18–24 °C (64–75 °F) were not associated with health risks ...
In special cases this can lead to confusion and errors. Good practice always incorporates the reference conditions of temperature and pressure. If not stated, some room environment conditions are supposed, close to 1 atm pressure, 273.15 K (0 °C), and 0% humidity.
Weather is a weather forecast app developed by Apple Inc., available on iOS since the release of the iPhone and iPhone OS 1 in 2007. [1] [2] It allows users to see the conditions, forecast, temperature, and other related metrics of the device's current location, as well as a number of other cities.
While further AI features are set to roll out over the next year, here are five major ones included in Monday's massive iOS 18.1 update, as seen on an iPhone 16 Pro Max. The 'writing tools ...
