A
copper
B
iron
C
aluminum
D
porcelain
Based on the information in the table, aluminum would be the best material to store the cold juice.
To determine the best material for storing the cold juice, we need to analyze the properties of each material listed in the table.
The table provides the coefficients of thermal conductivity for copper, iron, aluminum, and porcelain. Thermal conductivity refers to a material's ability to conduct heat. The higher the thermal conductivity, the better the material will transfer heat. However, in this case, we want a material that will keep the cold juice cool for the longest time, meaning we need a material with low thermal conductivity.
From the provided options, the material with the lowest thermal conductivity is porcelain with a value of 0.05. Therefore, the best material to store the cold juice would be porcelain (option D).
To determine which type of material would be the best one to store the cold juice based on the information in the table, you would need to consider the thermal conductivity of each material. Thermal conductivity measures how well a material can conduct heat.
First, locate the thermal conductivity values for each material in the table. The thermal conductivities are as follows:
- Copper: 397 W/m·K
- Iron: 80 W/m·K
- Aluminum: 237 W/m·K
- Porcelain: 1.98 W/m·K
The lower the thermal conductivity value, the better a material is at insulating and keeping the cold juice cool for a longer period of time.
By comparing the values, you can see that porcelain has the lowest thermal conductivity value of all the materials listed (1.98 W/m·K). Therefore, the best material to store the cold juice would be porcelain (option D).
