A student poured 100 ml of water (density = 1.00 g / mL) into a coffee calorimeter, noted that the temperature of the water was 18.8oC, then added 5.33 g KOH. With the lid on, the mixture was stirred, temperature increased and the maximum temperature reached at the time of mixing 31.6 oC. Calculate the heat of the system in this dissolution reaction (qsys). ( Approximate the specific heat capacity, cp as 4.18 J g-1 K-1. Do not consider the contribution to the heat generated from the calorimeter; assume that this is zero. Only calculate the heat from the heat capacity of the solution. make sure you consider the sign of qsys qsys for dissolution of KOH = J

As some of you know, I am an aficionado of Starbuck's Steamed Milk, Venti size. Steamed milk is made by passing superheated steam into a stainless steel container containing the milk. Assume that the stcam is at 25C,L-$40 calories/gram, and the specific heat of steam is 0.500 calories/gram/degree C. Also assume that the milk is at 5°C and that 750 ml of milk represent the Venti size. The stainless steel container can be considered to have a mass of 400. grams and a specific heal capacity of 0.600 Jgram/K. If the density of milk is its specific heat is 4.184 Vgram/K, how many grams of steam does it take to raise the milk's temperature to a comfortable 65 C? Thank you for your help!

An average man weighs about 70 kg and produces about 10460 kJ of heat per day. Suppose that a man was an isolated system and that his heat capacity was 4.18J/Kg; if his temperature were 37°C at a given time, what would be his temperature 24 h later? A man is in fact an open system, and the main mechanism for maintaining his temperature constant is evaporation of water. If the enthalpy of vaporization of water at 37°C is 43.4 kJ/mol, how much water needs to be evaporated per day to keep the temperature constant?
