Problem 37

Explain why a building made of bricks has smaller entropy than the same bricks in a disorganized pile. Do this by considering the number of ways that each could be formed (the number of microstates in each macrostate).

Step-by-Step Solution:
Step 1 of 3

Vectors Position and displacement vectors Vector Addition and subtraction Velocity and acceleration vectors Multiplying vectors Vector and Scalar  Vector: a quantity that has both magnitude and direction  Scalar: a quantity that has only magnitude How to express a Vector:  Graphical: An arrow with a magnitude and directions  Components: a component of a vector is the projection of the vector on an axis; the x- component and the y-component. o Magnitude is the square root of x + y 2  Unit vectors: a vector that has a magnitude of 1 and points in a particular directions; it specifies only a direction. Position Vector The Location of a particle relative to the origin is given by a position vector. Displacement Vector Displacement is the shortest distance from the initial to the final position Average velocity in 3 dimensions: Time (t) scalar Position (r->) vector Displacement: Δr->=r->-r-> 0 Time interval: Δt= t-0 Definitions  Acceleration: velocity is speeding up, slowing down, or changing direction  Speed: magnitude of the velocity vector  Speeding up: velocity vector’s magnitude is increasing  Slowing down: velocity vector’s magnitude is decreasing
