A 100 gram glass container contains 250 grams of water at 15.0 °C. A 200 gram piece of lead at 100 °C is added to the water in the container. What is the final temperature of the system? (specific heat of water = 4,186 J/kg °C, specific heat of glass = 837.2 J/kg °C, specific heat of lead = 127.7 J/kg °C)

A monatomic ideal gas at 27°C undergoes an isobaric process from state A to B, followed by an isochoric process from state B to C. What is the total work done by the gas in these two processes? (A = 2 atm, 1 L; B = 2 atm, 2 L; C = 1 atm, 2 L)

Work done on heating one mole of monoatomic gas adiabatically through 20°C is W. Then the work done on heating 6 moles of rigid diatomic gas through the same change in temperature
Ans 10w

Heat is supplied to 20lb of ice at 0°F at the rate of 160Btu/sec. How long will it take to convert the ice to steam at 213°C?

the magnitude of the gravitational force acting on an object is equal to ?

Steam flow Steadily Into condenser Enthalpy at entry bud exit are 2050 kj/kg and 200 kj/kg respectively. Velocity at entry and exit are 500 m/s and 10 m/s. Exit is in line with Entry . Determine Heat Transfer to cooling per unit mass of steam condensed.

A rectangular glass block 4.00cm×1.50cm×0.05×0.08 is situated in a liquid with the longest edges of the glass vertical and with the top side 2.00cm below the liquide.The density of the liquid is 0.85g/cm³.Calculate the magnitude of the pressure due to the liquid acting on the top and bottom faces of the block
