Answer:
Water needs more energy to bring a change in its temperature as compared to soil.
Explanation:
Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster. The reason behind it is the specific heat capacity of water that allows it hard to bring a change of 1 degree in its temperature.
The temperature of the soil will be higher than that of the water after six minutes.
Further explanation:
Properties are categorized into two types:
1. Intensive properties:
These properties depend on the nature of the substance and not on the size of the system. If the system is further divided into a number of subsystems, the values of intensive properties remain unchanged. Temperature, refractive index, molarity, concentration, pressure, and density are some of the examples of intensive properties.
2. Extensive properties:
These properties depend on the amount of the substance. These are additive in nature if a single system is divided into several subsystems. Mass, enthalpy, volume, energy, size, weight, and length are some of the examples of extensive properties.
Temperature:
It is a physical quantity that measures the hotness or coldness of any substance. It is an intensive property. The device used to measure temperature is a thermometer. Three common scales are there to measure temperature of a substance. These are Celsius scale, Kelvin scale, and Fahrenheit scale. SI unit of temperature is Kelvin (K).
Specific heat capacity is the amount of heat or energy required to increase the temperature of 1 kg of any substance by 1 K. It is denoted by c and its SI unit is [tex]{\text{J}} \cdot {\text{k}}{{\text{g}}^{ - 1}} \cdot {{\text{K}}^{ - 1}}[/tex].
Water has high value of specific heat capacity so it needs more energy so as to bring an increase in its temperature. But soil has low specific heat capacity than that of water. So it requires less energy to increase its temperature.
Therefore the temperature of the soil will be higher than that of the water.
