<span>Answer is:
the final temperature was 915 K.
p₁ = 1 atm.
T₁ = 305 K.
V₁ = 16 cm³
p₂ = 48 atm.
V₂ = 1 cm³.
T₂ = ?
Ideal law gas:
p₁V₁ / T₁ = p₂V₂ / T₂.
1 atm · 16 cm³ / 305 K = 48 atm · 1 cm³ / T₂.
T₂ = 305 K · 48 atm·cm³ ÷ 16 atm·cm³.
T₂ = 915 K.
p - pressure.of fuel air
T - temperature of fuel air.
V - volume of fuel air.</span>
According to Newton’s first law of motion,if there is no net force acting on an object that is moving at a constant 30 mph speed, the object will continue to move at 30 mph.
Option a
<h3><u>
Explanation:</u></h3>
"Newton's first law of motion" states that an object at a stationary position or an object moving at a constant velocity continues its state of rest or of motion unless it is acted upon by an "external unbalanced resisting force".
Since the net force acting on this object is zero; the absence of any kind of force (neither internal nor external) is observed and hence the motion at constant 30 mph velocity will continue until it is resisted.
Answer:
Gold is an element even when it is in a solution
Answer:
1. Why was the line of best fit method used to determine the experimental value of absolute zero?
The line of best fit method is used to determine the experimental value, because it most accurately shows where the line crosses the x-axis.
2. Which gas law is this experiment investigating? How does your graph represent the gas law under investigation?
This investigation is experimenting the “Ideal Gas Law”. This law by Gay-Lussac shows that when the volume in a container of a gas is held constant, while the temperature is increased, the pressure will also increase.
3. Using your knowledge of the kinetic molecular theory of gases, describe the relationship between volume and temperature of an ideal gas. Explain how this is reflected in your lab data.
As temperature increases, volume increases when pressure is held constant. As seen in the chart, as the temperature increases the volume in each gas also increases slightly.
4. Pressure and number of moles remained constant during this experiment. If you wanted to test one of these variables in a future experiment, how would you use your knowledge of gas laws to set up the investigation?
Supposedly at a constant temperature, the gas volume and pressure stay constant. Therefore, the amount of moles also remains constant. So perhaps, the temperature could fluctuate, meaning it will not only increase or decrease, but do both. This will avoid consistency and prove the Ideal Gas Law to be true.
