Question
1. There are two containers, A and B, of equal size. Gas that behaves ideally is in both containers and it is known that A has a temperature of 52ºC and B a temperature of 9.0ºC. Nothing else is known about the gasses. Which of the following statements must be true? Which could be true? (a) The pressure in A is higher than in B. (b) There are more molecules in A than in B. (c) A and B cannot contain the same type of gas. (d) The molecules in A interact with each other more than those in B interact with each other. (e) The molecules in A have more average kinetic energy per molecule than those in B. (f) The molecules in A are moving faster than those in B. Explain your reasoning behind your answers
Explanation / Answer
a,d,e & f must be true as the increased temperature increases the random motion of gaseous
particles which, in turn,increases the collision rate and hense the interaction
between two particles. These interaction tends to increase the pressure.
b might be true. More number of particle will cause more collision which in
turn, will cause more increase in temperature.
