What are the three properties of water? 1 Answer. The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. Why is hydrogen bonding important to life? Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible […]
Why are copper electrodes used in electrolysis?
Why are copper electrodes used in electrolysis? Aims. To investigate the electrolysis of copper sulfate solution using non-inert electrodes. Copper electrodes take part in the reactions and are described as non-inert: at the positive electrode, copper atoms lose electrons and form copper ions , Cu. What will happen during electrolysis of AQ CuSO4 using platinum […]
Why do electric motors rotate anticlockwise?
Why do electric motors rotate anticlockwise? Motor fans work by pulling air in from one direction, and pushing it out the other direction. Using two fans pitched in opposite directions allows you to have both fans push air the same direction, and rotate in opposite directions. Can you reverse the direction of a starter motor? […]
Which of the following statement is correct for waves?
What is the formula for calculating pipe size?
How does electronegativity increase?
How does electronegativity increase? The electronegativity of atoms increases as you move from left to right across a period in the periodic table. This is because as you go from left to right across a period, the nuclear charge is increasing faster than the electron shielding, so the attraction that the atoms have for the […]
What is the percentage of guanine in salmon?
What are the 5 motor skills?
What are the 5 motor skills? Gross motor skills include skills such as: sitting. standing. walking. running. jumping. lifting (a spoon, a hairbrush, a barbell — they all count) kicking. What is an example of a fine skill? They include many fundamental movement patterns such as walking, running, jumping and throwing. A tackle in rugby […]
What happens to the force between two charges if the distance between them is halved and doubled?
What happens to the force between two charges if the distance between them is halved and doubled? If the distance between them is doubled then the force is one-fourth of the original force. If the distance between them is halved then the force is four times than the original force. What happens to the force […]
How do you calculate static pressure?
How do you calculate static pressure? To determine operating total external static pressure. Measure pressures where air enters and leaves packaged equipment. Add the two readings together to find total external static pressure. You can still measure the pressure drop of the coil and filter to check for blockage. How many CFM is a 6 […]
