Answer: Nuclear Explosion hope this helpsss
Answer:
the final temperature is T2= -126.5°C
Explanation:
Since the gas behaves as an ideal gas
Initial state) P1*V1=n*R*T1
Final state) P2*V2=n*R*T2
where P= gas pressure , V=volume occupied by the gas , n= number of moles , R= ideal gas constant , T= absolute temperature
dividing both equations
(P2/P1)*(V2/V1)=T2/T1
since P2=2*P1 and V2=1/4*V1 , T1=20°C=293K
2*1/4=T2/T1
T2=T1/2 = 293K/2 = 146.5K
T2= 146.5K= -126.5°C
Answer:
Neptune
Explanation:
"Answer: Pluto is usually farthest from the Sun. However, its orbit "crosses" inside of Neptune's orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune's orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.

Work is measured in joules, so you're question was already answered! 75 joules of work was required.
However, if you're asking about the force that was required, you're answer would be 25 N of force.
work= force x distance
75= f x 3
75= 25 x 3
