A 0.730 kg block of ice at 0 deg C is placed into 1.92 L of water at 16.9 deg C.
How much ice is left when the system reaches equilibrium, in kg?
A 0.223 kg block of ice at 0 deg C is placed into 1.68 L of water at 21.6 deg C. What is the final temperature after all of the ice has melted and the system reaches equilibrium, in deg C?
Please Help!!!!
QUESTION 16 A 1.00 kg block of ice (specific heat 0.500 cal/g deg C) is removed from the freezer where it was kept at -13.2 degrees Celsius. How much heat energy (in cal) has it absorbed when its temperature is -5 degrees Celsius? QUESTION 17 How much heat energy (in cal) is required to heat the block from the previous problem from -5 deg Celsius to 0 deg Celsius?
A 2.0 kg block of -5.0° C ice is sitting on a surface with negligible conductivity. A heater is located nearby. Assume the following constants Lf = 334 kJ/kg, Lv = 2260 kJ/kg, cice = 2093 J/kg°C, cwater = 4186 J/kg°C, caluminum = 837 J/kg°C. a. How much heat is required to melt the ice completely? b. You want to vaporize the ice completely. i. How much heat is required? ii. Construct a temperature vs heat graph for the entire process. iii. Label the section...
1 kg block of ice at 0 degrees celsius placed in cooler. How much heat will the ice remove as it melts to water at 0 degree celsius. I know the answer is 80kcal but don't know the math that backs up the answer-please help!

QUESTION 19 1.3 kg of ice at 0 deg C is dropped into a cooler containing 14 kg of water at 1 7 deg C. Given a latent heat of fusion of water/ice of 79.7 cal/g and a specific heat of water of 1.00 cal/g deg C, what is the final temperature of the mixture (in deg。? QUESTION 20 In a similar situation to the previous problem, what is the smallest mass of ice (in kg) at 0...
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.
A block of ice, mass 1.94 kg and initial temperature of -11 oC, is placed in an insulating container. 1.73 kg of water at temperature 20 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.
A 3.2 kg block of copper at a temperature of 82°C is dropped into a bucket containing a mixture of ice and water whose total mass is 1.2 kg. When thermal equilibrium is reached the temperature of the water is 8°C. How much ice was in the bucket before the copper block was placed in it? (Neglect the heat capacity of the bucket.) answer in kg
