2.1
A thermometer has a mercury filled glass bulb with a volume of 2 x 10-7 m³ attached to a thin glass
capillary tube with an inner diameter of 0.1 mm. If the temperature increases by 100K, calculate how far
will the mercury rise in the tube.

A 50 g silver disk at 300°C is placed in 200 cm' of methyl alcohol at 14°C, then removed quickly. The
silver temperature is found to have dropped to 120°C. Calculate the new temperature of the methyl
alcohol.
[HINT: Specific heat capacities of silver and methyl alcohol are, respectively, 235 J/(kg-K) and 2530
J/(kg-K), and density of methyl alcohol is 792 kg/m³]

A 0.25 mol of a monatomic ideal gas at 27°C is contained in a cylinder that is fitted with a movable
friction free piston. The temperature of the gas is increased to 127°C while the pressure of 1 atm is
maintained. Calculate:
i.
how much work is done by the gas
in the
process,
ii.
the change in internal energy of the gas,
ii.
heat that was supplied to the gas.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b154d49-3819-42dc-8e12-b65b9ba6f23d%2F42ff034b-175a-4d82-94a6-ae3acef37dab%2Fri81ubm_processed.jpeg&w=3840&q=75)
