10. what is heat transfer?
Jawaban:
heart transfer dalam istilah medis ialah transplatasi hati yang dilakukan tenaga medis untuk menunjang pasokan darah serta aliran ginjal dari paru-paru menuju hati, namun istilah heart transfer dalam istilah psikologi berartikan metode psikologis dengan menyatukan suara hati ke hati untuk memberikan afeksi dan efek nyaman dan mengenal masing-masing individu.
11. Can heat transfer by convection in a solid? why?
heat transfer in a solid is called conduction, not convection. because convection is heat tansfer in a gas and a liquidDapat perpindahan panas secara konveksi di padat? kenapa?
karena perpindahan secara konveksi bisanya di zat cair dan gas

18. An uninsulated steam pipe passes through a room where the air and walls are 25°C. The outer diameter of the pipe is 70 mm, and the surface temperature and emissivity are 200°C and 0.8, respectively. What is the radiated power and surface irradiation? If the coefficient of free convection heat transfer from the surface to the air is 15 W/m²K, what is the rate of heat loss from the surface per unit length of pipe?
Jawaban:
Travel via. Candyman glad dollar.
19. Conduction is the method of heat transfer in solids but not liquids and gases. Why?
Jawaban:
Konduksi adalah metode perpindahan panas dalam padatan tetapi
bukan cairan dan gas. Mengapa?

20. Can anyone help me please The top surface of the passenger car of a train moving at a velocity of 70 km/h is 2.8 m wide and 8 m long. The top surface is absorbing solar radiation at a rate of 200 W/m, and the temperature of the ambient air is 30°C. Assuming the roof of the car to be perfectly insulated and the radiation heat exchange with the surroundings to be small relative to convection, determine the equilibrium temperature of the top surface of the car?
Jawaban:
iya, ini bukan fisika tapi bahasa inggris
