This law brings Boyle's, Charle's, Avogadro's, and Gay-Lussac's laws together in one neat, easy to use package: PV = nRT. Using simple algebra any of this variables can be isolated: P = nRT/V, V = nRT/P, T = PV/nR, n = PV/RT, or the ideal gas constant R computed. All gas calculations must be made using temperatures in Kelvin. If the ideal gas constant R = 0.08206 L∙atm/mol∙K, what volume will 1.00 mol of a gas occupy at 1.00 atm of pressure and 273 K?

22.4L

Explanation:

The following data were obtained from the question:

P = 1atm

T = 273K

n = 1mole

R = 0.08206 L∙atm/mol∙K

V =?

PV = nRT

V = nRT/P

V = (1 x 0.08206 x 273)/1

V = 22.4L

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
