you can maximise the rate of energy transfer by using materials that;
-are good conductors
-are painted Matt black
-have the air flow around them maximised
Styrofoam is a good insulator because it is made up of 95% air. This trapped air prevents the transfer of heat energy, keeping things cool by slowing down the rate of heat transfer from the environment to the contents inside the Styrofoam container.
transfer kinetic energy, leading to an increase in temperature of the cool object. This transfer of energy continues until both objects reach thermal equilibrium.
Convection is the primary type of energy transfer responsible for making you feel cold when swimming in cool water. As your body interacts with the cooler water, it absorbs heat, causing you to experience a sensation of coldness.
Air conditioning systems transfer thermal energy by absorbing heat from inside a space and releasing it outside. So, while air conditioning itself is not thermal energy, it does involve the transfer of thermal energy in order to cool a space.
This is an example of heat transfer from the warm water to the cold glass. The glass absorbs the thermal energy from the water, causing the water to cool down.

The universe wants to even out all the energy in it. Thus until this even state is reached, bodies that are warmer than this state will radiate electromagnetic heat energy and in doing so cool. Where the body is in contact with other matter, it will also transfer its micro kinetic energy to the matter around and in contact with it.
There are three ways thermal energy can be transferred: conduction, convection, and radiation.

Insulators are materials that don't transfer thermal energy easily. They have low thermal conductivity, which means they resist the flow of heat, helping to keep objects warm or cool by preventing the loss or gain of thermal energy. Examples of insulators include wood, plastic, and rubber.
The air will cool down, while the other object gets hotter.
true because its warm to cool which means it changes temperature
