What does temperature measure?

An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 4Kg of an ideal gas at 800Kpa and 50C and the other part is evacuated. The partition is now removed, and the gas expands in the entire tank. Determine the final temperature and pressure in the tank.

a magnesium hydroxide solution is prepared by adding 10.00 g of magnesium hydroxide to a volumetric flask and bringing the final volume to 1.00 l by adding water buffered such that the ph will remain at 7.0. what is the concentration of magnesium in this solution? (assume standard pressure and temperature and the ionic strength is negligible)

Two gaseous streams streams enter a mixing chamber through two sections and leaves through one section. At entrance; A1 = 450 cm2 , V1 = 150 m / sec , v1 = 0.625 m3 / kg , and A2 = 380 cm2 , V2 = 55 m / sec, ρ2 = 2 kg / m3 . At exit; V3 = 245 m / sec , and v3 = 0.58 m3 / kg. Draw the figure and determine; (a) the mass flow (kg / sec ) at section 2, and (b) the area of the exit section (cm2).

A separator accepts waste oil at 70% oil and 30% water by weight. The top product stream is pure oil while the bottom underflow contains 10% oil. If a flow of 20 gal/min is fed to the tank, how much oil is recovered?

Butane is burned with air. No carbon monoxide is present in the combustion produets.
Calculate the molar composition of the product gas for each of the following three cases: (i)
theoretical air supplicd, 100 % conversion of butane: (i) 20% excess air. 100% conversion of
butane: and (il) 33% excess air. 90% conversion of butane.

. For quick preparation of a cup of hot chocolate in a cafeteria, cocoa powder and sugar

are added in a cup of water and the solution is heated by direct steam injection. If the

initial temperature of all the ingredients is 15 ℃, the final temperature is 95℃, the mass

of the solution is 150g initially, and the heat capacity of the solution is 3.8 kJ/kg ℃,

calculate how much saturated steam at 110 ℃ will be used. State your assumptions.
