Question

just answer and discuss one

Review QAS a. Energy transfers by heat are induced only as a result of a temperature difference between a system and its surroundings. b. Work and heat are associated with the process, so they are point functions C. If a system undergoes a process involving heat transfer with its surroundings but no work, that process is said to be adiabatic. d. The change in the internal energy of a system between two states is the change in the total energy of the system between the two states, if neglect the changes of the system's kinetic and gravite potential energies between these states e. For every thermody et amounts of energy transfer by heat and equal.

Answer 1

Solution:

Energy Transferred by Heat as a result of the temperature difference between a system and surroundings.

It can be understood by the images is attached below. It has been an explanation and examples both.

Answer @ [Part a : by "Kerouth law of Thermodynamics says "uf two bodies are in Same tempenture then no heat in trausform between two bodiero when two bodies are in contact, Heat (2) as a form of Thermal Energy transformed from a hotter system to coller system • If there i tenerature difference between two bodies or in with dusoundings. Then, we Cat Calculate heat Released (ory heat abosredo m= mass of Substance. q (Heat Released ) = m*C*AT c= Specific heat Copacity Heat absorbed Tato change in tumperature. ( Cop) 10 -> Scientiest defines two heat as between thermal Energy transformed system at different temperature that comes un contact Heat Sumber 9 (or) Q. units - Joule (J) Explanation athen two bodies or a System Conca in it contact, Then starts to absorb or loses heat. The average Kinetic Energy of the molecules will change • Thus, Heat trausfer results in a change in the system's temperature as long as the system is not undergoing phase change phase charge un temperature from heat framfamed of a systan dipende how many moleculee present u System and heat Capacity of the System Mojo

Example to understand a cooling a cup of Tea ? Diet's say we have 250 ml of Tea at current temperature of 370 Kelvin we need to cool it before drinking - Find - How much Thermal Energy Cory Heat ho to be transformed to the surroundhigh to cool the tea? solution density of water is 1000 gm /mL. Specific heat Capacity of water 4010 J/g. R. mass=250ml * 1 gm = 250gm 02 AT=350k - 370k ATC - 20k q=m*CXAT = 250m* 4:18 * (-20k) I gmin [q. - 21000) of to " Thus, we Calculated that the Tea will trausfer 22000 Energy to the Sunandnige when it cooledown to 370k 350K.
