Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
This is the rating required to protect microfilm, microfiche, and other film-based information storage media. Above 150 °F (65.5 °C) film is distorted by the heat and information is lost. A Class 150-2 Hour vault must keep the temperature below 150 °F. for at least two hours, with temperatures up to 2,000 °F. (1,093.3 °C) outside the vault.

It was the Spaniards, drawn by the rumor of immense gold deposits in the Mambulao-Paracale district, who mastered in exploring the gold ...
To avoid this, some weather services require that all mercury-in-glass thermometers be brought indoors when the temperature falls to −37 °C (−35 °F). To measure lower meteorological temperatures, a thermometer containing a mercury- thallium alloy which does not solidify until the temperature drops to −61.1 °C (−78.0 °F) may be used.
The energy needed per unit distance increases by the square of the velocity and the time decreases linearly. However power increases by the cube of the velocity. For example, 2.37 times as much power is needed to travel at 400 kilometres per hour (250 mph) than 300 kilometres per hour (190 mph), while drag increases by 1.77 times the original ...
Stationary fuel cell applications typically require more than 40,000 hours of reliable operation at a temperature of −35 to 40 °C (−31 to 104 °F), while automotive fuel cells require a 5,000-hour lifespan (the equivalent of 240,000 km or 150,000 mi) under extreme temperatures.
