Answer:
This is because no energy is being created or destroyed in this system
Explanation:
I think this is correct? I hope it helps.
Answer:
C
Explanation:
Only this choice is applicable and correct.
The inter-molecular forces of attraction between the molecules must have been broken (overcome) before the molecules can gain an increase in the kinetic energies between them.
The new volume is 1.9 ml
<u><em> calculation</em></u>
The new volume is calculated using the combined gas equation
that is P1V1/T1 = P2V2/T2 where
P1= 1.0 atm
V1= 21 ml
T1 = 10.0 c into kelvin = 10 + 273 = 283 k
P2 = 15 atm
V2=? Ml
T2 = 120 c into kelvin = 120 +273 = 393 K
make V2 the subject of the formula by multiplying both side by T2/P2
V2=T2P1v1 / P2T1
V2=[(393 k x 1.0 atm x 21 ml) / (15 atm x 283 K)] = 1.9 Ml
Answer : The length of the ramp to the nearest inch will be, 129.49
Step by step explanation :
As we know that,
In the given image, the value of 
(the angle between the base and the hypotaneous) is 
and the value of perpendicular is 18 inch.
Now we have to calculate the value of the hypotaneous by using above expression, we get
The hypotaneous is equal to the length of the ramp = 129.49 inch
Therefore, the length of the ramp to the nearest inch will be, 129.49
