Please help 1. Calculate the increase of entropy (in J/K) when 42 g of ice melts at 0 ºC and 1 atm. (The heat of fusion for ice is 6,000 J/mol.) 2. Calculate the change in entropy (in J/K) when a 34.0 g of water is heated from 12.4 ºC to 70.5 ºC at 1 atm. (The specific heat is 4.184 J/(g-K).) Notice that entropy and heat capacity have the same units.
1)calculate the specific heat of 87.0 grams of a substance that when it absorbs 9,370 joules of heat, it increases in temperature from 15.0 degrees c to 75.0 degrees c 2) calculate the energy needed to heat 127.0 grams of water from 25 degrees c to 95 degrees c. assume that the specific heat for liquid water is 4.18 j/g degress c
5000 Joules of heat are added to 100 grams of water at 30 Celsius. Calculate the final temperature. Cpwater = 4.184 J/g C
When 55.0 grams of metal at 75.0°C is added to 100. grams of water at 14.0°C, the temperature of the water rises to 17.5°C. Assume that no heat is lost to the surroundings. What is the specific heat of the metal? The specific heat of water is 4.184 J/g·°C.

A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celcius is added to 50.00 grams of water initially at 11.1 degrees Celcius. The final temperature of the system is 20.15 degrees Celcius. Calculate the specific heat of the metal. (The specific heat of water is 4.184 J/g*C). JgoCJgoC
13.0 g of cream at 15.6 °C are added to an insulated cup containing 150.0 g of coffee at 74.5 °C. Calculate the equilibrium temperature of the coffee. You may assume no heat is lost to the cup or surroundings, and that any physical properties of cream and coffee you need are the same as those of water. Be sure your answer has 3 significant digits. °C x 5 ?
