. You are a chef at a restaurant and need to cook a pot of soup. To make sure the soup is cooked evenly and is at the right temperature, you need to know the heat transfer rate and the time it takes to cook. If the pot has a surface area of 0.2 m^2 and a thickness of 0.005 m, and the temperature difference between the soup and the air is 20°C, what is the heat transfer rate? If you want the soup to reach a temperature of 70°C and it starts at a temperature of 10°C, how long will it take to cook? (Units: heat transfer rate - watts (W), time - seconds (s), area - square meters (m^2), temperature - Celsius (°C), thickness - meters (m))
