Answer :
In a laboratory where the air temperature is 22°C, a steel cylinder at 100.°C is submerged in a sample of water at 40.°C. In this system, heat flows from the steel cylinder to the water, and the water to the container and air. This is because heat always flows from a higher temperature to a lower temperature.
Heat flows from steel cylinder to water and air and also from water to air.
Further Explanation:
The property is a unique feature of the substance that differentiates it from the other substances. it is classified into two types:
1. Intensive properties:
These are the properties that depend on the nature of the substance. These don't depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, concentration, pressure, and density are some of the examples of intensive properties.
2. Extensive properties:
These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, heat, energy, size, weight, and length are some of the examples of extensive properties.
Heat is the transfer of energy due to the difference in temperature between the system and its surroundings. Its direction of flow is always from a higher temperature to a lower one.
Given information:
The temperature of air is [tex]22\;^\circ {\text{C}}[/tex] .
The temperature of the steel cylinder is [tex]100\;^\circ {\text{C}}[/tex] .
The temperature of the water sample is [tex]40\;^\circ {\text{C}}[/tex] .
It is clear that the steel cylinder is at the highest temperature, followed by water sample, and the air temperature is the least among the three. As we know, heat always flows from a higher to lower temperature. So heat will flow from steel cylinder to both water and air. Then it will also flow from water to air.
