- 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 x 105 J/kg. Answer in units of °C. Your response... Previous Responses X #1.79.7 PALETTEIf a leaf is to maintain a temperature of 40.0°C (reasonable for a leaf), it must lose 250 W/m2 by transpiration (evaporative heat loss). Note that the leaf also loses heat by radiation, but we will ignore this. How much water is lost after 1.00 h through transpiration only? The area of the leaf is 0.00300 m2. Heat of vaporization for water is 2256 kJ/kg (see Table B.5).A 23 g ice cube at -15.0oC is placed in 129 g of water at 48.0oC. The Specific heat of ice is 2.090 J/g K, the specific heat of water is 4.186 J/g K, and the latent heat of fusion for water is 333 J/g. What is final temperature in celsius of the system when the equilibrium is reached. Ignore the heat capacity of the container and assume this is in a calorimeter.

To cool the body of a 75-kg jogger [average specific heat capacity = 3500 J/(kg · C°)] by 1.5 C°, how many 63. kilograms of water in the form of sweat have to be evaporated?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 CIn an insulated vessel, 239 g of ice at 0°C is added to 635 g of water at 15.0°C.
