You are warming up 2 kg of soup in a pot on a stove. The soup (C=4 kj/kg/K) starts at 4ºC. You have it on a heating element that is drawing 1.2 kW of power. 15% of the heat from the element is going directly to the air. Of the heat going into the pot, 20% is lost by heat transfer to the room. You are stirring vigorously and add 25 KJ of energy to the pot. How long will it take for your soup to reach 70ºC? Ignore the energy going into the pot.

You have placed a copper pot with water to heat on the stove. After one minute you place your finger in the water and you are okay. When you touch the pot your finger gets burned. Upload a drawing of a molecular view of what the copper atoms and water molecules look like at the beginning of heating the pot and after the pot has been heated for 15 mins.

A 0.250-kg aluminum bowl holding 0.800 kg of soup at 26.6°C is placed in a freezer. What is the final temperature if 430 kJ of energy is transferred from the bowl and soup? Assume the soup has the same thermal properties as that of water, the specific heat of the liquid soup is 1.00 kcal/(kg · °C), frozen soup is 0.500 kcal/(kg · °C), and the latent heat of fusion is 79.8 kcal/kg. The specific heat of aluminum is 0.215...

(8%) Problem 3: A 0.275-kg aluminum bowl holding 0.65 kg of soup at 25.0°C is placed in a freezer.What is the final temperature, in degrees Celsius, if 377 kJ of energy is transferred from the bowl and soup, assuming the soup’s thermal properties are the same as that of water? Specifically, you can assume the latent heat of fusion for the soup is 334 kJ/kg.

Part A A copper pot of mass 2.5 kg contains 5.2 litres of water (i.e. 5.2 kg) at room temperature (200C). An iron block of mass 9.4 kg is dropped into the water and when the system comes into thermal equilibrium, a temperature of 380C is measured. What is the initial temperature of the iron block? Give your answer in oC to three significant figures. Part B Iron has a specific heat that is larger than that of copper. A...
