A physics student adds water to an insulated bucket of ice. The ice is at an initial temperature of -15 ∘C, and the water is at 20∘C. If the bucket contains 6.0 kg of ice, what mass of water should the student add so that exactly half of the ice melts? Neglect the specific heat of the bucket.
A Styrofoam bucket of negligible mass contains 1.55 kg of water and 0.435 kg of ice. More ice, from a refrigerator at -15.0 ∘C, is added to the mixture in the bucket, and when thermal equilibrium has been reached, the total mass of ice in the bucket is 0.772 kg . Assuming no heat exchange with the surroundings, what mass of ice was added?
4. You drop 500 g of solid ice at 0°C into a 2 kg bucket of water at 40°C. Eventually everything comes to thermal equilibrium. A) What is the final temperature of the system? B) How much heat flowed into the ice? ) What was the entropy change of the ice that turned into water?
Initially you have mW = 3.4 kg of water at
TW = 54°C in an insulated container. You add
ice at TI = -21°C to the container and the mix
reaches a final, equilibrium temperature of Tf
= 25°C. The specific heats of ice and water are
cI = 2.10×103J/(kg⋅°C) and
cW = 4.19×103 J/(kg⋅°C),
respectively, and the latent heat of fusion for water is
Lf = 3.34×105 J/kg.

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
ue term -10° C to 25° C? 30.0 kg of water is contained in a 10.0 kg aluminum pot. Both the water and the pot are initially at 20° C. How much heat (in Joules) is required to raise the temperatures of the water and pot to 105° C? 2. How much heat (in Joules) is required to raise the temperature of 20.0 kg of ice from-10° C to 0° C if half of the ice (10.0 kg) is converted...
IP A 1.0-kg block of ice is initially at a temperature of -5.0 ∘C. A) If 2.9×105 J of heat are added to the ice, what is the final temperature of the system? B) Find the amount of ice, if any, that remains.
