a)A piece of iron block moves across a rough horizontal surface
before coming to rest. The mass of the block is 3.3 kg, and its
initial speed is 3.2 m/s. How much does the block's temperature
increase, if it absorbs 74% of its initial kinetic energy as
internal energy? The specific heat of iron is 452 J/(kg ·
°C).

b)Some stove tops are smooth ceramic for easy cleaning. If the ceramic is 0.590 cm thick and heat conduction occurs through an area of 1.31 ✕ 10−2 m2 at a rate of 2271 J/s, what is the temperature difference across it (in °C)? Ceramic has the same thermal conductivity as glass and brick.

A piece of iron of unknown mass has an initial temperature 210∘C. It is dropped into an aluminum container of mass 0.2 kg containing 1 litre (1.0 kg) of water both of which are at a temperature of temperature 20 ∘C . The final equilibrium temperature of the system when energy transfer between the iron and the water finally stops is 28.5 ∘C. (Assume no thermal energy gets lost.) What is the mass of the iron piece? Express your answer...
