How does a cooler use thermal conductivity to keep things cold?

cooler works on the principle of evaporative cooling. Evaporation is the process of converting liquid in to vapour . In this process some part of heat is absorbed and stored (latent heat) resulting in decrease of temperature.
We can feel this effect in our daily lives , like sweating in summer gives us cooling effect to body

What factor determines how hot or cold something feels when you touch it?
The temperature. Also, thermal conductivity.
Which way does thermal energy travel?
From the hotter to the cooler
What can a thermal insulator not do?
A thermal insulator is totally incapable of answering this question
What are 3 things that produce thermal energy?
heat waremth cold war
Why is a cool bag suitable to keep hot things hot and cold things cold?
Hot things get cooler, and cold things get warmer, because they exchange heat with their surroundings. A "cool bag", whatever that is, is apparently designed in such a way as to prevent that (probably it's insulated).
Which factor most determined how hot or cold something feels when you touch it?
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
How do you keep things warm and cold?
Well, you could put something hot in a thermos, and something cold in a cooler bag, wich is basically lined with thermal material. Things kept in thermal things won't stay the same temperature forever.

From the hotter to the cooler
Does rubber conduct cold?
Nothing conducts cold, really. Materials conduct heat, rather than the lack of it, and rubber has a low thermal conductivity, and is therefore considered a thermal insulator.
When something is heated does the thermal energy go from the cooler to the warmer object or from a warmer object to a cooler object?
hot to cold
Does thermal conductivity play a role in the development of residual stresses in metal?
Answer In most applications, I would not expect Thermal conductivity to be a factor. Only in applications where the part is exposed to extreme heat or cold or large fluctuations in temperatures under loads.
What can a thermal insulator not do?
A thermal insulator is totally incapable of answering this question
What is a example for conductivity?
Non Examples of conductivity are: plastic, aluminum, wood, etc. Plastic, aluminum and wood don't get cold really easly! By the way, things that have conductivity are things that conduct heat. Non Examples of conductivity are things that do not conduct heat. Hope this helped!(:

Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
Where can I find a travel cooler and warmer that keeps things both hot and cold?
You can find a travel cooler and warmer that keeps things both hot and cold at amazon.com, www.crateandbarrel.com, www.keepyourcooler.com, and sears.com.
