Suppose you have 2.5 kg of steam occupying 6.5 m^3 at a pressure of 1.013 x 10^5 Pa. When the steam condenses to water, it occupies a volume of 0.55 m^3 If the latent heat of vaporization of water is 2.26 x 10^6 j/kg, what was the change in the water's internal energy? AT = 0
m = 2.5 kg
V. = 6.5 m^3
P = 1.013 x 10^5 Pa
Vf= 0.55 m^3
L = 2.26 x 10^6 j/kg
Q is coming out of the system
W is done on the system​

i believe the answer is a hope it and is correct

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
