Two identical blocks are heated to different temperatures. The blocks are placed so that they touch, and heat begins to flow bet
ween blocks. The pair of blocks is insulated, so no energy escapes.
Lastly, the temperature of each block is measured again. Which pair of temperatures is possible?

Answer:
No. of moles, n = 25.022 moles
Given:
Volume of gas in tank, V = 29.1 l
Temperate of gas, T = = 273 + 35.8 = 308.8 K
Pressure of gas, P = 21.8 atm
Solution:
Making use of the ideal gas equation which given as:
PV = nRT
where
R = Rydberg's constant = 0.0821 L-atm/mol-K
Re-arranging the above formula for 'n' and putting the values in the above formula:
n = 25.022
