Hello everyone!
I just had a quick question on heat transfer and change in volume. One problem states that a rubber balloon moves from the bottom of a tank of fluid to the top. The temperature of the fluid remains constant. It asks what causes the decrease in temperature in the balloon as the balloon moves up?
I can see how the pressure is reduced, thus allowing the volume of the balloon to increase and perform work. However, I don't get why there isn't any heat exchange. One solution said that this is because of the uniform temperature of the water. I'm not sure I really understand what that means. Any help is appreciated!
Thanks!
