The statements that describe a property contributing to the difference in temperature between the two samples of gas are:
B. the particles in sample A have a higher average speed than the particles in sample B.
Temperature is related to the average kinetic energy of the particles in a sample of gas. If the particles in sample A have a higher average speed, it indicates that they have higher kinetic energy, which correlates to a higher temperature.
The other options do not directly relate to the difference in temperature:
A. the total mass of sample A is higher than the total mass of sample B - This statement does not contribute to the temperature difference, as temperature depends on the average kinetic energy per particle, not the total mass.
C. Each particle in sample A has more mass than each particle in sample B - Even if particles in sample A are more massive, it is still the average kinetic energy of the particles (which is influenced by both mass and speed) that determines the temperature. Thus, this statement is not a direct contributor to the temperature difference without additional information about their speeds.
So, the correct answer is **B**.
