Initial Conditions:
Volume= v1= 417 cm³
Temperature= T1 = 278 K
Final Conditions:
Temperature= T2 = 231K
Volume = v2 =?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
As, the temperature is constant;
So,
v1/T1 = v2/T2
417/278 = v2/231
v2= 346.5 cm³
Answer:
the answer is A
Explanation:
Hopefully u get the answer right
Explanation:
Expression for the kinetic energy is as follows.
K.E = 
Now, total kinetic energy will be as follows.
K.E = 
= 
Since, this energy converts into electromagnetic radiation of wavelength 121.6 nm.
Relation between energy and photon is as follows.
Energy of photon = 
= 
= 
v = 
= 
m/s
Thus, we can conclude that atoms were moving at a speed of m/s before the collision.
Answer:
403 Seconds in Minutes is about 6 minutes.
Explanation:
Now, because I don't know if you're labeling your 1500 as meters or miles, I'm assuming it's miles.
I'm going to take a gander at your question.
Since you're technically going so fast for some odd reason.
Your answer should most definitely be 403 MPH
I'd go for D here. It also fits in with the idea of thermal expansion - as something is heated up, molecules vibrate and maybe collide. they vibrate with bigger amplitudes, so taking up more space, so expanding. maybe
