a man takes brick out of fire at 285C he drops it in a bucket of water and hen covers the bucket. the bucket and cover are amade of insulating materials. the bucket contains 2.6kg of ice originally at -5C. the 1.3kg brick is made out of iro with a specific heat capacity of 448J/kg.C. find the temp of the brick and water when equilibrium is reached.

8 grams of oxygen at STP is compressed adiabatically to a pressure of 10 atm .How much work id done on the gas

Calculate the depth in the ocean at which the
pressure is three times atmospheric pressure.
Atmospheric pressure is 1.013 × 105 Pa. The
acceleration of gravity is 9.81 m/s2 and the density of sea water is 1025 kg/m3.
Answer in units of m.
Don't round answer.

how many calories are required to convert 100 grams of ice to steam?

200 kPa is equal to what

Consider systems which obey the following physical statistics: any number of particles can occupy any energy levels( assuming that they are accessible). The energy levels are equally spaced such that for the nth level, En=nE0 where n=0,1,2,3,... and E0 is a positive constant. All particles are distinguishable. Assume that the system 1 has an energy 4E0 and contains N (>>1) particle. System 2 has an energy level of E0 and also contains N particles. For each system, enumerate the possible states and find the probability That each system will be found in a particular energy distribution. B). If the two systems are brought into thermal contact ( thus allowing them to exchange energy freely( but not particles), determine the value of the multiplicity function for all possible configurations of the combined system . What is the most probable configuration of the combined system? How much more probable is it that we would find the system in its most probable configuration compared to any other configuration?.

one gm of ice at 0 degree c contracts in volume by 0.091 cm^3 on melting.9 gm of metal is heated to 200 c and dropped into an ice calorimeter.The decrease in volume was found to be 0.182 cm^3.Calculate the specific heat capactity of metal.

Air flows steadily at the rate of 0.4 kg/s through an air compressor, entering at
6 m/s with a pressure of 100 kPa and a specific volume of 0.85 m3
/kg. The air
exits at 4.5 m/s with a pressure of 690 kPa and a specific volume of
0.16 m3
/kg. The specific internal energy of the air leaving is 88 kJ/kg greater
than that of the air entering. Cooling water in the jacket surrounding the
cylinder absorbs heat from the air at the rate of 59 kJ/s. Calculate:
a. The power required to drive the compressor
b. The cross-sectional area of the inlet pipe
c. The cross-sectional area of the outlet pipe

Determine the quantity of heat required to convert 1kg of ice formally at -20°c to water at 100°c and steam at 100°c
