A block of wood is sliding across a rough surface. The block has a mass of 10.0 kg and is moving with an initial speed of 10.0 m/s. It slides across the surface and comes to rest. The kinetic energy of the block has been converted into heat. Assume that the block and the surface are at a constant temperature of 293 K. (a) What is the kinetic energy of the block? (b) How much heat has been deposited in the block and the surface? (c) What is the change in entropy? (d) Is this a reversible process?

An unknown substance has a mass of 0.125 kg and an initial temperature of 94.5°C. The substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water initially at 25.5°C. The mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium.temperature of 32.0°C. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance. J/kg - °C Need Help?

a 183 degree celsius aluminium block was dropped in 100 degrees celsius water. as a result, the water gained 82,000 J of heat until thermal equilibrium was reached. during this time some, but not all, of the water boiled and turned to steam. assume the water and aluminium make up a closed system and determine how much water turned to steam, and the aluminiums mass. Specific heat of aluminium is 900 J/kg*K steam to water latent heat = 2,260,000 J/kg*K ice to water latent heat = 333,000 J/kg*K Please include the units, and round to the fourth decimal point.
The air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when 1 cubic meter of water cools by 1.0°C will raise the temperature of an enormously larger volume of air by 1.0°C. Estimate that volume of air. The specific heat of air is approximately 1.0 kJ/kg ? °C. Take the density of air to be 1.3 kg/m3.
Suppose you have 2.5kg of steam at 100 degrees celcius occupying 6.5 meters cubed at a pressure of 1.013 x 10^5 Pa. When the steam condenses to water at 100 degrees celcius it occupies a volume of 0.55 meters cubed. If the latent heat of vaporization of water is 2.26 x 10^6 J/kg, what was the change in the water's internal energy?
A (9.20x10^1)-kg block of ice at 0.00°C breaks off from a glacier, slides along the frictionless ice to the ground from a height of 2.43 m, and then slides along a horizontal surface consisting of gravel and dirt. Find how much in grams of the mass of the ice is melted by the friction with the rough surface, assuming 75.0% of the internal energy generated stays in the ice. Latent heat of fusion (Lf) for water 333,700 J/kg. Provide your answer to three significant figures.
Radioactive decay of elements in the earth’s interior results in a mean heat flux through the Earth’s surfaceof 5×10−2Wm−2. What is the flux expressed as a fraction of the energy flux due to thermal re-radiation of absorbed solar energy? If radioactive decay were the only heat source for the Earth, what would the Earth’s temperature be?
