2 litres of mercury at 80 deg.Celsius is pushed into a plastic bucket containing 10 litres of mercury at a temperature "T".if the final temperature of the mixture is 30 degree Celsius ,what is the value of "T".(neglect any heat loss to environment)

The highest recorded temperature on Krypton was 142 degrees F. The lowest recorded tempera-
ture was −93 degrees F.
Express the low temperature extreme in degrees Celsius.
Answer in units of degrees C.

Integratee the given PdV expressions to get W1-2 and W 3-1 AND Note that for a total cycle qcycle=W CYCLE{Otherwise there would be a net change in the energy and it wouldn't be a steady state}

How do i solve this problem using the thermodynamic structure?

How can we evaluate the change in density between the given pressure when melting point of tin at pressure of 1 bar is 505K, but increases to 508.4K at 1000 bar?
please tel the steps and formulas used.

a) Calculate the Stoichiometric air/fuel ratio for the complete combustion of Octane (CH8H18)

b) Determine the Excess air factor , if a dry volumetric analysis of the products of this fuel is

CO2 9% ; CO 2% ; N2 89%

c) It is necessary to reduce the dewpoint to below 15degree C by diluting the exhaust products with air. Calculate the dilution ratio moles air/mole of exhaust.

Show that (dH/dP)s=V

Steam at 1.00MPa and 350ºC enters a diffuser steadily with a velocity of 400m.s-1, and leaves at
2.75MPa and with a velocity of 40.0m.s-1. During transit through the diffuser, 1.5kJ.kg-1 of heat
is lost to the atmosphere.
(a) What is the specific enthalpy of the entering steam? (2 marks)
(b) Determine the specific enthalpy of the exit steam? (6 marks)
(c) Determine the exit temperature of the steam. (2 marks)
(d) What is the ratio of the inlet to exit area (A1/A2)? (5 marks)
Clearly state any assumptions you make.
