Since the question has pressure, temperature, and volume as variables, in order to arrive at an answer the combined gas law will be needed to arrive at an answer. The Combined Gas Law is a combination of Boyle's Law (pressure and volume are inversely proportional when temperature is constant) and Charle's Law (volume and temperature are proportional when pressure is constant) and is used when neither volume, pressure nor temperature is constant.
Combine Gas Law Equation: P₁V₁ ÷ T₁ = P₂V₂ ÷ T₂
The following values are what is known from the question:
the initial pressure (P₁) = 1 atm; the final pressure (P₂) is 0.5 atm,
the initial volume (V₁) = 300 mL or 0.3 L; the final volume (V₂) = 1 L
the initial temperature (T₁) = 27 °C
then we can substitute these into the equation to find the final temperature (T₂).
P₁V₁ ÷ T₁ = P₂V₂ ÷ T₂
∴ by substituting the known values,
⇒ (1 atm) (0.3 L ) ÷ (27 °C) = (0.5 atm)(1 L) ÷ T₂
⇒ T₂ = [ (0.5 atm) (1 L) (27 °C) ] ÷ (1 atm) (0.3 L )
⇒ T₂ = [13.5 atm · L · °C] ÷ [0.3 atm · L]
⇒ T₂ = 45 °C
Thus the new temperature of the gas is 45 °C.
Dang that is a lot of work lol
Answer:
I dunno, what is the answer
Explanation:
Hello there,
The answer to your question is:
C. Zinc
Hope this answer helps you.
To find the speed, you're going to find the miles per hour. So, you divide the total amount of miles traveled by the time it took to travel those miles.
1200/30
Now you have a fraction. But, this fraction can be reduced, so now we have to reduce it. Both the denominator and the numerator can be divided by 30.
40/1
So, your answer is forty miles per hour.
