The pressure exerted by a gas is 2.0 atm while it has a volume of 350 ml. what would be the volume of this sample of gas at standard atmospheric pressure?

volume is 700 mL

Explanation:

pressure = 2 atm

volume = 350 mL = 0.350 L

to find out

volume

solution

we will apply here equation that is

P1×V1 = P2×V2   1

here P1 = 2 and V1 = 0.350 and P2 = 1 for standard atmospheric pressure

so put all value here  in equation 1 and get V2 volume

2 × 0.350 = 1 × V2

V2 = 0.700 L

V2 = 700 mL

so volume is 700 mL

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
