Six objects are placed in a 2303 C oven and allowed to reach thermal equilibrium; Each object has a mass of 1 .0 kg. The specific heat and thermal conductivity of each substance are denoted by c and k. Part A Rank these objects on the basis of their temperatures when removed from the oven. Rank from largest to smallest. To rank items as equivalent, overlap them. View Available Hint(s) Hint 1. Specific heat The specific heat of a substance is the amount of heat energy needed to raise the temperature of 1.0 kg of the substance by 1" C. Hint 2. Thermal conductivity The thermal conductivity of a substance is a measure of the rate at which heat energy can flow through a substance. A substance with large thermal conductivity allows the rapid flow of heat energy through it. Hint 3. Equilibrium At equilibrium, an object and its surroundings are at the same temperature.Reset Help aluminum pot well done steak glass casserole dish iron skillet silver ingot c = 900 J/(kg .

The tubs are quickly sealed and insulated. Rank the objects on the basis of their temperature on reaching equilibrium with the water. Bank from largest to smallest. 11: rank Items as equivalent. overlap them. v View Available Hlnt[s} V Him 1. IGonsenration of energy Once placed in contact with the cold water, heat energy will flow from the hot objects into the cold water, lowering the temperature of the objects and raising the temperature of the water. Objects that can transfer a large amount of heat energy with a small change in temperature will end up with the highest equilibrium temperatures. 7 Him 2. Energy transfer and specific heat An object that can transfer a large amount of heat energy with a small change in temperature has a large specific heat.

C) largest smallestPart B When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how hot they feel. Rank from largest to smallest. To rank items as equivalent, overlap them. View Available Hint(s) Hint 1. Sensing temperature The rate at which heat energy flows into (or out of) your body will determine how hot (or cold) something feels when you touch it. For example, if heat energy flows rapidly from your hand when you touch an object, the object will feel very cold. Hint 2. Rate of heat flow The rate of heat flow (via conduction) AQ/ At from one point to another depends on the temperature difference AT', between the points, the area A and thickness L of the contacting surface, and the thermal conductivity k of the surface. Mathematically, this can be represented as A? = KA(AT).Reset Help iron skillet well done steak silver ingot glass casserole dish aluminum pot c = 448 J/ (kg .' C) c = 3500 J/(kg .C) c = 235 J/(kg .
