The correct Answer is:
To answer the question regarding the key abiotic factors that lead to variation in the physical and chemical conditions of different habitats, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Abiotic Factors**: - Abiotic factors are the non-living components of an environment that influence the living organisms present. They include elements such as light, temperature, water, soil, and atmospheric pressure. 2. **Identify Key Abiotic Factors**: - The key abiotic factors that significantly affect habitats are: - **Light**: It is essential for photosynthesis in plants and affects the behavior and distribution of organisms. - **Temperature**: It influences metabolic rates and physiological processes in organisms. - **Water**: It is crucial for all living organisms, affecting their survival, reproduction, and distribution. - **Soil**: The composition and quality of soil affect plant growth and, consequently, the entire food web. 3. **Evaluate the Options**: - Now, let's analyze the provided options: - **Option 1**: Light, temperature, and water - This includes key abiotic factors. - **Option 2**: Soil, pressure, and humidity - While soil is relevant, pressure and humidity are not primary factors compared to the first option. - **Option 3**: Producer, consumer, and decomposer - These are biotic factors, not abiotic. - **Option 4**: Light, pressure, and predation - Pressure is not a key abiotic factor, and predation is a biotic factor. 4. **Select the Correct Option**: - Based on the analysis, **Option 1 (Light, temperature, and water)** is the correct answer as these are the primary abiotic factors that lead to variation in the physical and chemical conditions of different habitats. ### Final Answer: The key abiotic factors that lead to so much variation in the physical and chemical conditions of different habitats are **light, temperature, and water**. ---

Chemical reactions are invariably associated with the transfer of energy either in the form of hear or light. In the laboratory, heat changes in physical and chemical processes are measured with an instrument called calorimeter. Heat change in the process is calculated as: q= ms Delta T , s= Specific heat = c Delta T = Heat capacity. Heat of reaction at constant pressure is measured using simple or water calorimeter. Q_(v)= Delta U = Internal energy change, Q_(P) = DeltaH, Q_(P) = Q_(V) + P Delta V and DeltaH = Delta U+ Delta nRT . The amount of energy released during a chemical change depends on the physical state of reactants and products, the condition of pressure, temperature and volume at which the reaction is carried out. The variation of heat of reaction with temperature and pressure is given by Kirchoff's equation: (DeltaH_(2) - DeltaH_(1))/(T_(2)-T_(1))= Delta C_(P) (At constant pressure), (DeltaU_(2) - DeltaU_(1))/(T_(2)-T_(1)) = DeltaC_(V) (At constant volume) The enthalpy change (DeltaH) for the reaction N_(2) (g) + 3H_(2)(g) rarr 2NH_(3)(g) is -92.38kJ at 298 K.
