Explanation

When dealing with gases, we often use the Gas Laws to relate the variables of pressure, volume, and temperature. In this case, we are given the initial volume, temperature, and asked to find the temperature at which the volume is doubled while keeping the pressure constant. The most suitable gas law to use here is Charles's Law.

Charles's Law states that for a given amount of gas with a constant pressure, the volume of the gas is directly proportional to its temperature in Kelvin (K). Mathematically, this law is represented as:

\[\frac{V_1}{T_1} = \frac{V_2}{T_2}\]

Where \(V_1\) and \(T_1\) are the initial volume and temperature, and \(V_2\) and \(T_2\) are the final volume and temperature, respectively.

In this question, we are given:

• \(V_1 = 2 \, dm^3\)
• \(T_1 = 300K\)
• \(V_2 = 2V_1 = 4 \, dm^3\)

We are asked to find the final temperature, \(T_2\). Using Charles's Law, we can plug in the values and solve for \(T_2\):

Cross-multiplying and solving for \(T_2\), we get:

So the correct answer isOption D: 600K.

Correct Answer: D. 24

Explanation

The median is the middle number of the set, when it is listed in order from smallest to largest or vice versa. In this case we have an even amount of numbers in the set meaning there are two middle numbers- 23 and 25. In order to find the median we take the average of 23 and 25: (23+25)/2=24
