a 50g ice cube at -45o Cis placed in 200g of water at 5o C. If the final equilibrium temperature of the mixture is 0o C, how much water will freeze onto the ice?

A length of thin wire is placed over a block of ice (or an icecube) at 0°C. The wire hangs down both sides of the ice,and weights are hung from the ends of the wire. It is foundthat the wire cuts its way through the ice cube, but leaves asolid block of ice behind it. This process is called regelation.Explain how this happens by inferring how the freezingpoint of water depends on pressure.

A 6.00 kgm piece of solid copper metal at an initial temperature To is placed with 2.00 kgm of ice that is initially at -20.0°C. The ice is in an insulated container of negligible mass and noheat is exchanged with the surroundings. After thermal equilibrium is reached, there is 1.20kgm of ice and 0.80 kgm of liquid water. What was the initial temperature of the piece ofcopper?

What mass of water at 22.0°C must be allowed to come to thermal equilibrium with a 1:80 kg cube of aluminum Initially at 150"C to lower the Leimperature of the aluminum to 66.0°C? Assune any water turned to steam subsequently recondenses. kg Need Help? Read It

If 4.00 × 104 J of heat energy is required to turn water ice at −10.0º C to steam at 100º C, what was the mass of the block of ice? Note– this is not a sublimation problem.

An insulated beaker of negligible mass contains 0.250 kg of water at a temperatureof 75.0◦C. How much ice at a temperature of 0.00◦C must be dropped in so the finaltemperature of the system will be 30.0◦C?

A brass rod is 0.600 m long at 30o What is the length of the rod if it is heated to 100o C? [a of brass = 19 x 10-6  oC-1]

a cup of coffee sits on a table in an insulated mug. to coool the coffee down a ice block is added. the inital mass of coffee in the mug is 90g. the intial temperature of the coffee is 90 degree celsius. the ice block has started to melt and is then put into the coffee. the ice melts and the new temperature of the cofee is 78 degree c and the new mass is 110g. the ice block (final-intital mass) is 20g. what are teh tempeartuare changes for the coffee and ice (started at 0 degree celsius) also if specific heat of water is used for both the coffee and ice waht is the heat energy lost by the coffee and the heat energy gained by the ice after it melted?

Ur an exposed wheel diameter of 30.000 cm at a temperature of 15 C and the internal diameter of the iron rim of 29.930 cm. So to what temperature must the rim be heated in order for it to slide on the wheel? For this type of iron ('a = 1.10x10 c) %3D
