How do you calculate energy change? To calculate an energy change for a reaction: add together the bond energies for all the bonds in the reactants – this is the ‘energy in’ add together the bond energies for all the bonds in the products – this is the ‘energy out’ energy change = energy in […]
What happens if gas pressure is too high?
What happens if gas pressure is too high? High gas pressure can be just as bad for your furnace. That’s because it greatly increases the risk of furnace overheating. When this happens, all manner of internal components may become damaged by the excessive heat. What are four factors that determine the efficiency of a furnace? […]
Is electromagnetic force affected by intervening medium?
Is electromagnetic force affected by intervening medium? EM force does not need any intervening medium. Why is gravitational force independent of medium? Gravity is unipolar, attractive. So when it goes through a medium, there is no polarizing effect or polarizing forces. Thus the gravitational constant is independent of the intervening medium. Does electrostatic force depend […]

How does a fan convert energy?
How does a fan convert energy? (The fan’s blades move air around the room. The kinetic energy of the moving blades does work in moving air through the fan blades.) The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.) What does a fan do to […]
