Answer:

The answer to your question is 720.5°K

Explanation:

Data

Volume 1 = 285 ml

Temperature 1 = 355 °K

Pressure 1 = 1.88 atm

Volume 2 = 435 ml

Temperature 2 = ?

Pressure 2 = 2.5 atm

Formula

To solve this problem use the combined gas law

               P1V1 / T1 = P2V2 / T2

- Solve for T2

               T2 = T1P2V2 / P1V1

- Substitution

               T2 = (355)(2.5)(435) / (1.88)(285)

- Simplification

               T2 = 386062.5 / 535.8

- Result

                T2 = 720.53°K

Conclusion

The gas must be heated to 720.5°K

A toy rocket moving vertically upward passes by a 2.0-m-high window whose sill is 8.0 m above the ground. The rocket takes 0.15
sveta [45]

Answer:

v_i = 18.86 m/s

Explanation:

As we know that the speed of the rocket is v1 and v2 at the bottom and top of the window

then we will have

d = (\frac{v_1 + v_2}{2}) t

2 = (\frac{v_1 + v_2}{2})(0.15)

26.67 m/s = v_1 + v_2

also we know that

v_2 - v_1 = (-9.81)(t)

v_2 - v_1 = (-9.81)(0.15) = -1.47

now we have

v_2 = 12.6

also we have

v_1 = 14.1 m/s

now if the sill of the window is at height 8 m from the ground then we have

v_1^2 - v_i^2 = 2 a h

(14.1^2) - v_i^2 = 2(-9.81)(8)

v_i = 18.86 m/s
