Problem 11.68

A 50-g ice cube at 0C is heated until 45 g has become water at 100C and 5.0 g has become steam at 100C. How much energy was added to accomplish the transformation?

Step-by-Step Solution:

Step 1 of 3

Notes 11/7 Earth  Interior 1. Still has internal heating (partially molten core) 2. Differentiated: rock and metal are separated  It means, separating substances with different densities in liquid or gas (must be free to move around to differentiate)  Earth must have been completely molten long ago since it has differentiated  Early sources of heat 1. Impacts (gravitational energy heat) 2. Differentiation (from gravitational energy)  Current sources of heat 1. Radioactivity (U238)  How old is the earth  To find the age of a rock we need to know: 1. Current co
