Imagine two pure samples of gas in identical closed containers: sample A and sample B. Sample A has a higher temperature than sample B.Each of the statements below is true about the samples. Which statements describe a property that contributes to the difference in temperature? Select all that apply.

Answer 1

To determine which properties contribute to the difference in temperature between sample A and sample B, we can consider several aspects:

1. Average Kinetic Energy of Molecules: Temperature is directly related to the average kinetic energy of the molecules in a gas. If sample A has a higher temperature than sample B, it can be concluded that the average kinetic energy of the molecules in sample A is greater than that in sample B.

2. Molecular Speed: The speed of the molecules is also a factor; typically, higher temperatures correspond to higher speeds of the gas molecules. The average molecular speed in sample A would be greater than in sample B due to the temperature difference.

3. Type of Gas: If the two samples contain different types of gas, the molecular mass and specific heat capacity can influence how temperature is related to kinetic energy. However, for pure samples in identical containers, we typically focus on their kinetic energy.

4. Pressure: While pressure can influence temperature, in this scenario where temperature is already defined and compared, we primarily consider kinetic energy.

So focusing on properties that contribute to the actual temperature difference, the relevant statements you might select are:

• The average kinetic energy of the molecules in sample A is greater than that in sample B.
• The average speed of the molecules in sample A is greater than that in sample B.

If there are specific statements provided to choose from, please provide them, and I can help identify which specifically contribute to the temperature difference.
