A 0.012 kg cube of ice at 0.0°C is added to 0.477 kg of soup at 81.7°C. Assuming that the soup has the same specific heat capacity as water, find the fi- nal temperature of the soup after the ice has melted. The specific heat of water is 4186 J/kg °C and water's latent heat of fu- sion is 3.33 × 105 J/kg. Answer in units of °C. Your response... Previous Responses X #1.79.7 PALETTE

Final answer in decimal (like 0.0025 not 1.25x-0^-3). Unit for A is cm and B is C degree.

When a material changes phase - liquid, solid, gas- heat exchange is required. This heat is called the Latent heat. is the equation where L is the Latent heat and is material specific. How much heat is required to take water (mass of .55 kg) from -20 to 20 C? L for ice to water is 33.5 * 104 J/kg. the specific heat of ice is 2090 J/(kg*C).and for water is 4186 J/(kg*C).

Calculate the rate of heat conduction through house walls that are 13.0 cm thick and that have an avera thermal conductivity of 0.027W/m°C. Assume there are no windows or doors. The surface area of the walle is 120m? and their inside surface is at 18.0°C, while their outside surface is at 5.00°c

What is the ratio of the energy required to warm 125 g of Ice (0.0 \deg C) to body temperature (37 \deg C) to warming the same amount of water through the same temperature change? Answer format is the number Eice/Ewater = (2 significant figures) Latent Heat of Fusion of Water: 335, 000 J/kg Specific Heat Capacity of Water: 4186 J/kg/\deg C
