Two copper blocks, each of mass 1.96 kg, initially have different temperatures,t₁ = 17° C and t₂ = 27° C. The blocks are placed in contact with each other and come to thermal equilibrium. No heat is lost to the surroundings.

(a) Find the final temperature of the blocks.
°C

Find the heat transferred between them.
J

(b) Find the entropy change of each block during the time interval in which the first joule of heat flows.

ΔS₁	= J/K
ΔS₂	= J/K

(c) Estimate the entropy change of each block after it has reached thermal equilibrium. Use each block's average temperature during the process in calculating the estimated values of ΔS.

ΔS₁	= J/K
ΔS₂	= J/K

Two identical blocks of mass M = 2.60 kg each are initially at rest on a smooth, horizontal table. A bullet of very small mass m = 20 g (m << M) is fired at a high speed v. = 120 m/s towards the first block. It quickly exits the first block at a reduced speed of 0.40 v, then strikes the second block, quickly getting embedded inside of it. All the motion happens on the x-axis. (a) find the...

26/04/19 If two metal blocks of initially different temperatures come together and equilibrate to the same temperature and produce a total change in entropy of 6.2 JK^-1, what is the factor by which the number of microstates in the universe increases? Is this done using Boltzmann entropy? Also, please explain what the second law of thermodynamics is statistically based on.

A block made of copper with a mass of 0.90 kg is heated to 800°C, then dropped into 5.00 kg of water at 11°C. What is the total change in entropy (in J/K) of the block-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of copper is 387 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)

Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.20m , its speed is 1.50m/s . a. If the total mass of the two blocks is 16.0kg , what is the mass of the more massive block? Take free fall acceleration...

Given the mass of two blocks that collide, and the velocities of each block before and after the collision, be able to determine whether the collision was elastic, partially or completely inelastic, or not possible since an unnamed external force would be necessary to change the momentum, and/or kinetic energy of the system. Please explain in simplest terms and give an example using units given.
