Answer: New pressure inside the flask would be 148.8 kPa.
Explanation: The combined gas law equation is given by:

As the flask is a closed flask, so the volume remains constant. Temperature is constant also.
So, the relation between pressure and number of moles becomes



- Final conditions: When additional 3 puffs of air is added

Putting the values, in above equation, we get

The students have conducted an experiment to check their hypothesis on the thermal conductivity of two metals; Aluminum and steel. The experimental observations have been noted, and the next step based on the scientific procedure is to analyze the data.
Analysis of data suggests that; since the length of wax after 10 min is lower in Al than steel, aluminum is a better thermal conductor.
Ans B) Analyze the data
The scatter plot that shows a positive correlation between force and acceleration.
<h3>What is the relationship between acceleration of an object and the applied force?</h3>
The acceleration of an object is the change in velocity with time.
- Acceleration = change in velocity/time
Force is defined as an agent which causes a change in the motion or state of rest of a body.
According to Newton's law of motion, the rate of change of velocity of an object is directly proportional to the applied force and takes place in the direction of the applied force.
Force and acceleration have a positive correlation.
Therefore, the scatter plot which will most closely match the measurements that the students will obtain is that which shows a positive correlation between force and acceleration.
In conclusion, acceleration of a object is proportional to the applied force.
