*52. Go Three portions of the same liquid are mixed in a container thatprevents the exchange of heat with the environment. Portion A has amass m and a temperature of 94.0 °C, portion B also has a mass m but atemperature of 78.0 °C, and portion C has a mass me and a temperature of34.0 °C. What must be the mass of portion C so that the final temperatureT, of the three-portion mixture is T, = 50.0 °C? Express your answer interms of m; for example, mc = 2.20 m.

In 1986, a gargantuan iceberg broke away from the Ross Ice Shelf in Antarctica. It was approximately a rectangle 160 km long, 40.0 km wide, and 250m thick. a. What is the mass of this iceberg, in kilograms, given that the density of ice is 917 kg/m3 b. How much heat, in joules, must be transferred to the iceberg to melt it? Assume the ice is at 0° C, and the latent heat of fusion for water is Lf=79.8 kcal/kg c. How long, in years, would it take sunlight alone to melt ice this thick, if the ice absorbs an average of 100 W/m2, 12.00 hours per day?
S. At a temperature of 22.20°C the hole in a steel plate has a diameter of 1.030 cm. If a steel rod with a diameter of 1.038 cm has to just slip through this hole, to what temperature should the plate be heated? The coefficient of area expansion of steel is 24 X 10 -6/ °C. Ans: 672
3. A 3.2 m length of copper pipe extends directly from a hot-water heater in a basement to a faucet on the first floor of a house. If the faucet isn't fixed in place, how much will it rise when the pipe is heated from 20.0° C to 85.9° C. The coefficient of linear expansion for copper is 1.6*10-5 K−1.

You happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.
You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect
