1. A 200-L helium gas at a pressure of 2.00 atm was transferred to a tank with a volume of 68.0L. What is the internal pressure of the tank if the temperature is maintained? 2. Find the final temperature of a 2.00-L gas sample at 293.0 K cooled until it occupies a volume of 500mL.

Can someone help me pls I’m sitting here for hours :( I can’t really solve it right

i'm pretty sure its b i might be wrong though!

(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

plasma - state of matter made up of electrically charged particles
