What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]

Are opposite angles equal in a parallelogram? A parallelogram is a quadrilateral whose opposite sides are parallel. The opposite angles of a parallelogram are equal. The opposite sides of a parallelogram are equal. Are all angles in a parallelogram 90 degrees? A Parallelogram can be defined as a quadrilateral whose two s sides are parallel […]

How many coordinate systems are there? In this article we mainly discuss two types of coordinate systems. What is the difference between phi and theta? Theta is the same as the angle used in polar coordinates. Phi is the angle between the z-axis and the line connecting the origin and the point. How do you […]

What would you use to measure 1 mL of DI water? If it does not have to be exact, 1 drop from a eye drop or similar type device will be about 1ml. You can probably even use something like the tip of a pencil to form a droplet and that will be about 1ml. […]

Can nuclear waste be destroyed? It can be done. Long-term nuclear waste can be “burned up” in the thorium reactor to become much more manageable. Where does nuclear waste go? More than a quarter million metric tons of highly radioactive waste sits in storage near nuclear power plants and weapons production facilities worldwide, with over […]

Does reactivity increase left to right? Chemical reactivity of the elements – definition Period – reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. […]

Can you see North Star from equator? As you travel northward, Polaris climbs higher in the sky. If you go as far north as the North Pole, you’ll see Polaris directly overhead. If you get as far as the equator, Polaris sinks to the horizon. South of the equator, Polaris drops out of the sky. […]
