Explain how you can use boyle's law to determine the new volume of gas when its pressure is increased from 270 kpa to 540 kpa? the original volume of gas was 1 l. assume the temperature and number of particles are constant. what is the new volume?

 At a constant temperature and number of moles of the gas the product of PV is equal to some constant this is Boyle's law. At another set of condition of the same temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

V2 = P1 x V1 / P2

 V2 = 270 x 1 / 540

 V2 =0.5 L

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.
