    specific heat capacity help?

    1)A cup is made of an experimental material that can hold hot liquids without significantly increasing its own temperature. The 0.75 kg cup has an initial temperature of 36.5?C when it is submerged in 1.25 kg of water with an initial temperature of 20.0?C. What is the cup’s specific heat capacity if the final temperature is 24.4?C?

    2) brass is an alloy made from copper and zinc. a .59 kg brass sample at 98.0 DEGREE C is dropped into 2.80 kg of water at 5.0 degrees C. if the equilbrium temperature is 6.8 C, what is the specific heat capacity of brass?

    3) what is the final temperature when 0.032 kg of milk at 11 degrees c is added to 0.16 kg of coffee at 91 degree C? ASSUME THE SPECIFIC HEAT CAPACITIES OF THE TWO LIQUIDS ARE THE SAME AS WATER AND DISREGARD ANY ENERGY TRANSFER TO THE LIQUIDS SURROUNDINGS

    4)the air temperature above coastal areas is profoundly by the large specific heat capacity of water . how large of a volume of air can be cooled by 1.0 degree C if energy is transfered by heat from the air to the water, thus increasing the temperature of 1.0 kg of water by 1.0 degree C? THE SPEcific heat capacity of air is approx 1000.0 j/kgDEGREE C , and the density of air is approx 1.29kg/m^3.

    please show work and i will give you 10 points for the best answer =) thankssss
