A gas occupies 34.5 liters at a pressure of 345 torr what will be the volume of this gas if the pressure becomes 760 torr

THE NEW PRESSURE IS 15.5 L.

Explanation:

Using Boyle's law which states that the pressure of a given mass of gas is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

P1V1 =P2V2

P1 = 345 torr = 345/760 atm = 0.45 atm

P2 = 760 torr = 760/760 atm = 1 atm

V1 = 34.5 L

V2 = ?

Rearranging the variables, making V2 the subject of the formula, we obtain:

V2 = P2 V1 / P1

V2 = 1 * 34.5 / 0.45

V2 = 15.525 Litres

The volume of the gas when the pressure becomes 760 torr or 1 atm is 15.5 Litres

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
