Two equal size boxes, A and B, contain ideal gases. An inserted thermometer shows TA= 50°C and TB= 10°C. This is all we know about the gas in the boxes. Which of the following statements must be true? Could be true? Must be false? Explain your reasoning.
a) The pressure in A is higher than the pressure in B.
b) A and B do not contain the same type of gas.
c) The molecules in A have more average kinetic energy per molecule than those in B.
