The number density of gas atoms at a certain location in the space above our planet is about 1.00×1011 m−3 , and the pressure is 2.75×10 – 10 N/m2 in this space. What is the temperature there?

The number density of gas atoms at a certain location in the space above our planet is about 2.90 ✕ 1011 m−3, and the pressure is 2.40 ✕ 10−10 N/m2 in this space. What is the temperature (in °C) there? A high-pressure gas cylinder contains 60.0 L of toxic gas at a pressure of 1.43 ✕ 107 N/m2 and a temperature of 22.0°C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature (−78.5°C) to reduce the leak rate and pressure so that it can be safely repaired. What is the final pressure in the tank in pascals, assuming a negligible amount of gas leaks while being cooled and that there is no phase change?

Super Invar, an alloy of iron and nickel, is a strong material with a very low coefficient of thermal expansion (0.20×× 10^-6 celcius). A 2.5 m -long tabletop made of this alloy is used for sensitive laser measurements where extremely high tolerances are required. A) How much will this alloy table expand along its length if the temperature increases 7.0 C∘? Express your answer to two significant figures and include the appropriate units. B) How much will a 2.5-m-long table made of steel expand along its length if the temperature increases 7.0 C∘? Express your answer to two significant figures and include the appropriate units.
