Left Arrow Far right arrow and center left arrow
These three arrows are correct due to heat transfers to cooler temp environments which allows the expansion of speed for molecules in their environment.
arrow from liquid to atmosphere is correct
arrow from atmosphere to beaker must be reversed
arrow from beaker to atmosphere is correct
heat always flows from direction of higher to lower direction of temperature.
let the temperature of atmosphere be 66 F, beaker be 112 F, liquid be 98 F.
arrow from liquid to atmosphere is correct because heat flows from 98 F to 66 F.
arrow from atmosphere to beaker must be reversed because heat must flow from 112 F to 66 F.
arrow from beaker to atmosphere is correct as heat flows from 112 F to 66 F.
arrow from liquid to beaker must be reversed as heat flows from 112 F to 98 F.
First, anything with a temperature different than zero will irradiate temperature, so with this point of view, all the lines are correct, but let's ignore the radiation.
In the more classical heat transfer (by contact), the heat goes from the hot element to the cooler element, so for example, the lines that are correct in the picture are: water to atmosphere (because water is at 112°F and atmosphere is at 66°F)
Hand to the atmosphere (because the hand is at 98°F and atmosphere is at 66°F)
Al the other lines would be incorrect.
Heat transfer goes from hot to cold.
Starting from the left and going to the right:
Vertical arrow pointing up goes from hand temp 98 deg to air temp 66 deg: correct
Horizontal arrow pointing left from beaker liquid at 112 deg to air temp of 66 deg: correct.
Vertical arrow pointing up from hand at 98 deg to beaker liquid at 112 deg: incorrect.
Diagonal arrow pointing down to left from air at 66 deg to beaker liquid at 112 deg: incorrect.
Right vertical arrow pointing up from hand at 98 deg to air at 66 deg: correct.
The arrow that starts on the palm and ends at the number 112; the arrow in the middle pointing straight up
