Answer: Clay, sand and silt characteristics
Explanation: I found the picture and the rest of your question.
Soil identification as sandy clay
Soil Texture indicates the composition of that soil by which it shows the amount of clay, sand, and silt.
That is a classification instrument and it's used in laboratories to show soil classes. This identification is showing soil class by the characteristics of silt, clay, and sand.
Soil texture can be defined by feel method or hydrometer methods for example.
Characteristics:
Answer: 3 Calories of heat will be required by silver to raise the temperature to 1°C.
Explanation: Specific heat is defined as the heat required to raise the temperature by 1°C for 1 gram of substance.
Mathematically,
where,
q = heat required = ? Cal
m = Mass of the substance = 50 g
c = Specific heat of the substance =
= Change in the temperature = 1°C
Putting values in above equation, we get:
