The relation between volume and temperature is direct, this is the higher the temperature the higher larger the volume.
Therefore, if you want that your gas occupies a larger volumen, you should increase the temperature, assuming other conditions (pressure and number of moles) remain unchanged.
The new temperature may be calculated using the proportion:
V1 / T1 = V2 / T2
=> T2 = V2 * T1 / V1
T1 and T2 are in absolute degrees, so T1 = - 73 + 273.15 = 200.15 K
=> T2 = 360 ml * 200.15 K / 210 ml = 343
Answer: the temperature should be increased to 343 K
Answer:
Explanation:
350 N force stretches the spring by 30 cm
spring constant K = 350 / 0.30 = (350 / 0.3) N / m
To calculate work done by a spring force we proceed as follows
spring force when the spring is stretched by x = Kx
This force is variable so work done by it can be calculated by integration
Work done by it in stretching from x₁ to x₂
W = ∫ F dx
= ∫ Kx dx with limit from x₁ to x ₂
= 1/2 K ( x₂² - x₁² )
Putting the given values of x₁ = 0.50 m , x₂ = 0.8 m
Work done
= 1/2 x (350 / 0.3)x ( 0.80² - 0.50² )
= 227.50 J

<em>The correct answer is option</em><em> B.</em> The maximum height that can be reached by the stone is determined as 11.5 m.
<h3>
Maximum height attained by the stone </h3>
The maximum height attained by the stone when it is a 2/3 of its total height is calculated as follows;
v² = u² - 2gh
where;
- v is final velocity at maximum height, v = 0
- u is initial velocity
- g is acceleration due to gravity
0 = u² - 2gh
2gh = u²
h = u²/2g
h = (15²)/(2 x 9.8)
h = 11.48 m
h = 11.5 m
Thus, the maximum height that can be reached by the stone is determined as 11.5 m
