Explanation Given info: The temperature range for system A is 25 o C to 35 o C , the temperature range for system B is 35 o C to 45 o C , the temperature range for system C is 45 o C to 50 o C and 35 o C and the temperature range for system D is 50 o C to 55 o C . The formula to calculate the change in entropy is, Δ S = Δ Q T (1) Here, Δ Q is the amount of heat added to the water. T is the average temperature of the water. The formula to calculate the temperature is, T = T f + T i 2 Here, T f is the final temperature. T i is the initial temperature. The formula to calculate the heat input is, Q = m c ( T f − T i ) Here, m is the mass of the water. c is the specific heat of water. Substitute m c ( T f − T i ) for Q and T f + T i 2 for T in equation (1) to find the value of Δ S . Δ S = m c ( T f − T i ) T f + T i 2 (2) Substitute 35 o C for T f and 25 o C for T i in equation (2) to find the value of Δ S A . Δ S A = m c ( ( 35 o C − 25 o C ) + 273.15 K ) 35 + 273.15 K+ 25 + 273.15 K 2 = 283.15 m c 303.15 = 0.93 m c Thus, the change in entropy of system A is 0.93 m c . Substitute 45 o C for T f and 35 o C for T i in equation (2) to find the value of Δ S B

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of en…

When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture? B
