1. The pressure on 2.50L of an enclosed gas changes from 105kPa to 40.5kPa. If the temperature remains unchanged
what is the new volume?
2. A gas with a volume of 3.50L at a pressure of 200kPa is
allowed to expand to 14.0L. If the temperature remains
unchanged what is the new pressure?
3. A sample of gas occupies 5.00L at a temperature of 27
degrees celsius. What will its volume be at 127 degrees
celsius if the pressure remains the same?

What is the most stable monatomic ion formed from nitrogen

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
