Answer:
<u>At 268.82°C</u> volume occupied by nitrogen is 10 liters at pressure of 900 torr.
Explanation:
Given:
Volume of a sample of nitrogen = 5.50 liters
Pressure = 900 torr
Temperature = 25°C
To find the temperature at which the nitrogen will occupy 10 liters volume at same pressure.
Solution:
Since the pressure is kept constant, so we can apply the temperature-volume law also called the Charles Law.
Charles Law states that the volume of a gas held at constant pressure is directly proportional to the temperature of the gas in Kelvin.
Thus, we have :
∝ 
where 
is a constant.
For two samples of gases, the law can be given as:
From the data given:
We need to find 
.
Plugging in values in the formula.
Multiplying both sides by .
Multiplying both sides by 
Thus, at 268.82°C volume occupied by nitrogen is 10 liters at pressure of 900 torr.

The ball is accelerating
Explanation:
On a distance-time graph, the slope of the graph represents the speed of the object represented.
Let's therefore calculate the slope (so, the speed of the ball) in the two intervals given.
In the first second, we have:
So the average speed is
In the next second, we have:
So the average speed is
We notice that the speed of the ball has increased from 20 m/s in the first second to 40 m/s in the next second: this means that the speed of the ball is increasing, and therefore, the ball is accelerating.
