How many pounds of nitrogen per acre are needed for corn? 250 pounds How much nitrogen do you put in a hay field? “Apply 50 to 60 pounds per acre of nitrogen on your best grass stands and 30 to 40 pounds per acre on the rest,” he recommends. Thomas suggests a similar amount of […]
What is CP and CV for water?
What is CP and CV for water? Specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure). What is CP and CV? The […]
Is hail a solid or liquid?
When a device is used in a circuit in which the voltage is 81V?
How do electrolytic cells work?
How do electrolytic cells work? An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. What […]
What is the difference between synoptic and prognostic charts?
What is the difference between synoptic and prognostic charts? 2. How are prognostic charts different from synoptic weather maps? Prognostic charts are computer generated forecast showing the expected pressure pattern at a specific future time. Synoptic weather maps describe the state of the atmosphere over a large area at a given moment. What is good […]
What is chemical energy for kid?
What is chemical energy for kid? Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. What is chemical energy 7th grade? chemical energy: Energy that is stored in the chemical bonds of molecules. This energy is released during chemical […]
What is the relationship between volume and pressure for a gas?
What is the relationship between volume and pressure for a gas? It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured. Are volume and temperature directly proportional? The volume of a […]
What are the 5 steps of the hydrologic cycle?
What are the 5 steps of the hydrologic cycle? Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously. Why is hydrologic cycle important? The hydrologic cycle […]
What are two examples of colloids?
What are two examples of colloids? Examples of colloid are mayonnaise, milk, butter, gelatin, jelly, muddy water. What are the 4 types of colloids? The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many […]
