Why do gas furnace efficiencies jump from 80 percent to 90 percent? Why do gas furnace efficiencies jump from 80% to 90%? Efficiencies over 80% cause condensation but the flue gas is still too hot for PVC vent pipe until the efficiency reaches 90%. Why does this gas require a 100% shutoff? Because they are […]
What are three factors that affect the rate of chemical reaction?
What are three factors that affect the rate of chemical reaction? Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate. What must happen before a chemical reaction can begin quizlet? What must happen before a chemical reaction […]

What is the definition of relativity?
What is the definition of relativity? 1a : the quality or state of being relative. b : something that is relative. 2 : the state of being dependent for existence on or determined in nature, value, or quality by relation to something else. Why is it called the theory of relativity? Einstein’s theory gets its […]
What is difference between frequency and intensity in exercise?
What is difference between frequency and intensity in exercise? Each element is important for ensuring you maximize your workouts so you experience health and fitness benefits. Frequency measures how often you complete your workouts and intensity measures how hard your body is working during each of those training sessions. What is difference between dB and […]
What are the function of receptors?
What are the function of receptors? Receptors are a special class of proteins that function by binding a specific ligand molecule. When a ligand binds to its receptor, the receptor can change conformation, transmitting a signal into the cell. In some cases the receptors will remain on the surface of the cell and the ligand […]
What are the names of the 4 heart chambers?
What are the names of the 4 heart chambers? The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and […]
How can you tell if glass is toughened?
How can you tell if glass is toughened? Check the Glass Edges Compared to standard annealed glass, which typically has edges that are rougher to touch, tempered glass is fairly smooth, if you run your hand along the edge of a sheet. This is one of the most common distinguishing features between annealed glass and […]
Is 2.4 GHz good for streaming?
What happens if a neutrino hits an atom?
What happens if a neutrino hits an atom? In a study published Thursday in Science, Collar’s group observed a new type of neutrino interaction: a neutrino bumping into an atomic nucleus, a process known as coherent elastic scattering. They just get close, and then the neutrino transfers a tiny bit of energy to a neutral […]
