The law of heat exchange, also known as the second law of thermodynamics, states that heat will naturally flow from a higher temperature to a lower temperature until equilibrium is reached. This principle governs the direction in which heat is transferred between objects and systems.
No, in an adiabatic process, the system does not exchange heat with its surroundings. This means that any change in the internal energy of the system is solely due to work done on or by the system, without any heat transfer. The term "adiabatic" specifically refers to conditions where heat exchange is prevented.
calorimeters should have a low heat capacity
The device you are referring to is called a calorimeter. It is specifically designed to measure the heat exchange between substances in a thermally isolated environment.
Low-density polyethylene (LDPE) is a poor conductor of heat. It has low thermal conductivity, which means it does not transfer heat efficiently. This property makes LDPE suitable for insulation applications, as it helps maintain temperatures by reducing heat flow. Overall, LDPE is primarily an insulator rather than a conductor of heat.
There are only heat receptors. "Cold" is a low level of heat.
Since the question is about heat exchange, I assume it is a man made. The first form of heat exchange is cooking. The first fluid is then water.
An adiabatic process is when there is no heat exchange with the surroundings. This means that no heat is added or removed from the system during the process.

The recommended heat setting to simmer the dish is low heat.
Countercurrent exchange maximizes heat transfer between two fluid streams by maintaining a steep concentration gradient throughout the exchange process, resulting in more efficient heat transfer. This mechanism allows organisms to conserve energy by reclaiming heat from outgoing fluids and transferring it to incoming fluids. It is commonly seen in biological systems like fish gills and mammalian kidneys to optimize heat exchange and maintain homeostasis.
Although cardboards heat capacity is not as low as that of papers it is still very low.
It has heat exchange.
Heat transfer fluids are necessary in many systems because they help regulate and control the temperature during the heat exchange process. They have high specific heat capacities and thermal conductivities, allowing for efficient transfer of heat. They also help prevent corrosion, have low freezing points, and can be tailored for specific temperature requirements.
An example of a substance with low specific heat is metal, such as iron or aluminum. These materials heat up quickly when exposed to heat and cool down quickly as well, due to their low specific heat capacity.
Low Heat in cooking is 225°F to 249° F.
calorimeters should have a low heat capacity
Which of these expressions you might use depends on what kind of heat you are cooking on. "Low flame" is something you would say if you have a gas stove, and "low heat" suggests an electric one. I have not heard "low fire" but it might be used by people who cook on open fires (a rare thing these days).
