A certain gas is present in a 13.0 L cylinder at 4.0 atm pressure. If the pressure is increased to 8.0 atm the volume of the gas decreases to 6.5 L . Find the two constants k1, the initial value of k, and kf, the final value of k, to verify whether the gas obeys Boyle’s law by entering the numerical values for k1 and kfin the space provided. Express your answers to two significant figures separated by a comma.   B.)If a certain gas occupies a volume of 17 L when the applied pressure is 8.5 atm , find the pressure when the gas occupies a volume of 4.3 L . Express your answer to two significant figures and include the appropriate units.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
