- An sulated container holds 100g of water at 30C. A 50g ice cube at 0C is dropped into the water and no heat is allowed to enter or leave the ice water container. What is the final termperature and thermodynamic state of the system after it comes to equilibrium. Hello. This is a practice problem I'm working on and I'm not sure if I'm aproaching the problem correctly. Thank you for the help.To keep warm outdoors, your run a 1118W generator for 4 minutes to make yourself a 300mL cup of tea. If the water only warmed up 60.02°C during this time, how efficient is the process?SKIN temperatures (57 C)the iatent neat or vap moi water ny of watch p=998.2 kg/m'. 3. Assume that the thickness of the tissue between the interior and the exterior of the body is d =3 cm and that the average area through which conduction can occur is A =1.5 m². Find heat transferred by conduction per hour if temperature difference between the inner body and the skin is AT = 2°C. Coefficient of thermal for tissue without blood is K. = 18 × 10-2 Cal /m-hr-ºC.
- An aluminum rod is 18.2 cm long at 20°C and has a mass of 350 g. If 12,000 J of energy is added to the rod by heat, what is the change in length of the rod? (The average coefficient of linear expansion for aluminum is 24 x 10-6 (°C)-1.) mmA 0.288-kg coffee mug is made from a material that has a specific heat capacity of 930 J/kg C° and contains 0.319 kg of water. The cup and water are at 25.6 °C. To make a cup of coffee, a small electric heater is immersed in the water and brings it to a boil in two minutes. Assume that the cup and water always have the same temperature and determine the minimum power rating of this heater. Number i Units
