What mass of ice would it take to lower the temperature of 0.5kg of water from 20°C to 0°C. 7. A 100-g piece of iron is heated to 100°C and then dropped into a cavity in a large block of ice at 0°C. How much mass of ice will melt? 8. 50 grams of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C. The final temperature of the water in the...
) What is the final equilibrium temperature when 40.0 grams of ice at -12.0°C is mixed with 20.0 grams of water at 32.0°C? The specific heat of ice is 2.10k]/kg C, the heat of fusion for ice at O'C is 333.7 kJ/kg, the specific heat of water 4.186 kJ/kg C, and the heat of vaporization of water at 100°C is 2,256 kJ/kg. How much energy will it take to cool the water to 0 °C? How much energy will it...
A block of ice, mass 3.21 kg and initial temperature of -15 oC, is placed in an insulating container. 3.22 kg of water at temperature 25 oC, is added to the container. The water and ice exchange heat, but no other heat flows into or out of the container. In the process of the water and ice reaching equilibrium, how much ice melts? Give your answer in kg to three digits.
A block of ice, mass 2.16 kg and initial temperature of -8 oC, is placed in an insulating container. 3.12 kg of water at temperature 24 oC, is added to the container. The water and ice exchange heat, but no other heat flows into or out of the container. In the process of the water and ice reaching equilibrium, how much ice melts? Give your answer in kg to three digits. Note: It is possible that the answer is zero.
What is the mass of ice (in g) at 0 °C that can be completely melted into liquid water at 0°C by a 119 g aluminum block at temperature 112 °C? Assume the aluminum block can melt the ice until its temperature drops to 0 °C. The heat capacity of aluminum is 0.903 J g-1 °C-1 and the heat of fusion of water is 6.02 kJ mol-1. Express your answer to 3 significant figures.
How much ice (in grams) would have to melt to lower the temperature of 351 mL of water from 26 ∘C to 6 ∘C? (You must consider the enthalpy in cooling the water, as well as the enthalpy in melting the ice and the enthalpy to heat the melted ice from 0∘C up to the system's final temperature of 6 ∘C. Also assume that the density of water is 1.0 g/mL.)
A quantity of frozen water (also called ice) of mass 0.0360 kg is initially at a temperature of -4.000 C. It undergoes a series of physical changes at atmospheric pressure. The specific heat of ice is 2090 J/kg.°C The specific heat of water is 4186 J/kg.°C The specific heat of steam is 2010 J/kg.°C. The heat of fusion of water is 3.33 105 J/kg. The heat of vaporization of water is 2.26 106 J/kg. (a) Calculate the amount of heat...
A 6.5g mass of ice with a temperature of 0 degree C is dropped Into Lake Erie, which is at a temperature of 15 degree C. What will be the final temperature, in Celsius, of the lake plus the ice? (You don't need to enter units. Just the numerical part of the answer.) If the latent heat of fusion of ice is 334kJ/kg and the specific heat of water is 4.18kJ kg-1 K-1 how much heat, in Joules, must 8.6g...
8. You have a large insulated container of water at 20°C. You place a 0.5kg 100°C piece of lead (specific heat 0.031cal/g.K) in the water. You also place a 0°C piece of copper (specific heat 0.092cal/g.K) in the water. What is the mass of the copper if the equilibrium temperature is 20°C?
An ice cube of mass 8.5 g at temperature 0∘C is added to a cup of coffee, whose temperature is 90 ∘C and which contains 130 g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice (the heat associated with ice melting) is 6.0 kJ/mol. Find the temperature of the coffee after the ice melts.(in C)
