What happens to an ionic compound when it is dissolved in water? a liquid crystals are formed. b the ions separate and conduct electricity. c the ions combine and conduct electricity. d the electrons are combined with the water molecules.

Match each scenario to the form of energy it represents

Find the mass by adding the numbers from the three sliders

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
