Answer:
Explanation:
Here, we want to calculate the final volume
We use the general gas equation here:
P1 is the initial pressure which is 0.850 atm
V1 is the initial volume which is 4.25 L
T1 is the initial temperature which is (23 + 273.15 = 296.15 K)
P2 is the final pressure which is 1.50 atm
V2 is the final volume which is unknown
T2 is the final temperature (11.5 + 273.15 = 284.65 K)
Substituting the values, we have:
<span>The answer is C)
mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9

Answer:
V₂ = 1070 mL or 1.07 L
Solution:
Data Given;
P₁ = 1170 mmHg
V₁ = 915 mL
T₁ = 24 °C + 273 K = 297 K
P₂ = 842 mmHg
V₂ = ?
T₂ = - 23 °C + 273 K = 250 K
According to Ideal gas equation,
P₁ V₁ / T₁ = P₂ V₂ / T₂
Solving for V₂,
V₂ = P₁ V₁ T₂ / P₂ T₁
Putting Values,
V₂ = (1170 mmHg × 915 mL × 250 K) ÷ (842 mmHg × 297 K)
V₂ = 1070 mL or 1.07 L
Answer:
frequency it the measure of the wave length. The measure of the peaks and troughs is how you measure the frequency. the distance between these is the wave length.
