An insulated Thermos contains 130 cm³ of hot coffee at 88.0°C. You put in a 19.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg-K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm³. Number i 66.63 Units C°

A chunk of hot iron is pulled out of a fire and placed between aluminum vice grips.  The mass of the iron is 219 g and the mass of the aluminum is 66.4 g.  The iron is initially 351.8 °C.  The aluminum is initially 24.7 °C.  Assuming no loss of heat to the environment, what is the final temperature of the iron-aluminum system? I couldn't even get started on this one.

The temperature of a aluminum bar rises by 10.0°C when it absorbs 4.73 kJ of energy by heat. The mass of the bar is 525 g. Determine the specific heat of aluminum from these data.

You have 975 grams of liquid water in a 275 gram glass container. Initially, the water and the container both have a temperature of 22.5 °C. You would like to cool the water and the container to a final temperature of 10.5 °C. You have a large supply of ice, which is initially at 0 °C. How much ice would you need to add to the container in order to get the desired final temperature after the ice melts and thermal equilibrium is reached? Give your answer in grams. The specific heat of liquid water is 4,186 J kg-1 °C-1, the specific heat of glass is 845 J kg-1 °C-!, and the latent heat of fusion of water is 333,500 J kg-!. Assume that the glass + liquid water + ice is an isolated system (i.e., no heat flows in or out of the system during this process).

A 6.25 kg block ice at 0 degrees Celsius is being warmed on a glass stove top. The thermal conductivity of the glass is 1.00 W/ (m K) and the glass is 0.50 cm thick. If the radiator plate underneath the glass raises the temperature of the bottom of the glass to 125 degrees Celsius, how long would it take to completely melt the ice? Assume the ice remains a solid rectangle with a square base of side 15 cm as it melts.   B. What is the rate of entropy change in Joules/ Kelvin/ seconds of the melting ice?

A parcel of air with a volume of 9.3 x 10 km that contains 4.8 x 10 kg of water vapor rises to an altitude where all the water in the parcel condenses and then freezes. What is the change in temperature of the parcel of air due to freezing? Assume the density of air at the condensation altitude is 7.2 x 10 g/m. The specific heat of air is 0.17 cal/g Co, the latent heat of vaporization of water is 540 cal/g, and the latent heat of fusion of water is 80 cal/g.)
