Agas is stored in a cylinder at a pressure of 6.0x10^5 n/m^2 and at a temperature of 10°c will be the change of the volume of the gas at 35° c if the pressure of the gars does not change?

0.34 x 10^-3 m^3

Explanation:

P1 = 6 x 10^5 N/m^2

T1 = 10 degree C = 10 + 273 = 283 K

T2 = 35 degree c = 35 + 273 = 308 K

Pressure remains constant , P2 = P1

P1 V1 = R T1

V1 = (8.314 x 283) / (6 x 10^5) = 3.92 x 10^-3 m^3

Now, let the Volume is V2

P1 V2 = R T2

V2 = (8.314 x 308) / (6 x 10^5) = 4.26 x 10^-3 m^3

Change in volume, v = V2 - V1 = (4.26 - 3.92) x 10^-3 = 0.34 x 10^-3 m^3

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
