a 10.0 g ice cube in 40.0 g of water at 30.0 c. The system is in a container with negligible heat capacity and is insulated from the surroundings. a) Find the equilibrium temperature and describe the contents in terms of the phase. b) If instead two ice cubes are added, find the equilibrium temperature and describe the contents in terms of the phase.

Q.13 What happens if you add heat to water that is at the temperature of 100°C? Does the temperature change? Explain.

Part A Assume all termperatures to be exact, and neglect significant figures for small changes in dimension. A steel beam 18 m long is installed in a structure at 16 "C. What is the beam's change in length when the temperature reaches -26 °C? Express your answer using two significant figures. ?. AL = mm Submit Request Answer Part B What is the beam's change in length when the temperature reaches 49 °C? Express your answer using two significant figures. AL- mm

A closed box is filled with dry ice at a temperature of -78.5 degreesC while the outside temperature is 21.0 degrees C the box is cubical measuring 0.4 m on a side and the thickness of the walls is 2.50 x 10^-2 m in one day 2.90 x 10^6 J of heat is conducted through the six walls find the thermal conductivity of the material from which the box is made
