Atank containing liquid butane and one containing liquid propane are sitting adjacent to one another. each tank is equipped with a regulator with a pressure gauge. classify these statements as true or false. the pressure reading for the butane tank is higher than that for the propane tank. the pressure readings will change when more liquid is added to the tanks. if the tanks are placed outside and the sun warms each tank to 46 , the pressure readings will be higher than they were initially. if an equal number of moles of gas is allowed to escape rapidly from each tank, the temperature of the butane tank will be lower than that of the propane tank.

Explanation:

The pressure reading for the butane tank is higher than that for the propane tank is False.  

The pressure readings will change when more liquid is added to the tanks is False

If the tanks are put outside and the sun warms each tank to 46, the pressure levels will be greater than they were originally True When an equal number of moles of gas will easily exit from each tank, the butane tank temperature will be smaller than that of the propane tank True.

(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
