Why does temperature increase volume?
Why does temperature increase volume? Another way to keep the pressure constant as the volume increases is to raise the average force that each particle exerts on the surface. This happens when the temperature is increased. So if the number of particles and the pressure are constant, temperature is proportional to the volume. When the […]

How does shape affect diffusion?
How does shape affect diffusion? Diffusion is like going through a net or sieve. Smaller sizes and shapes pass through more easily than large ones. What is the relationship between cell size and diffusion? The surface-to-volume ratio of a sphere is 3/r; as the cell gets bigger, its surface-to-volume ratio decreases, making diffusion less efficient. […]
Is rear-wheel drive good?
Is rear-wheel drive good? RWD vehicles handle much better than front-wheel drive vehicles and you will notice the difference in curves, turns, and when navigating through traffic situations. Traction won’t be as good, especially in wet or snowy road conditions. Is rear wheel drive bad in rain? As anyone who has owned one will tell […]

What is the purpose of thin layer chromatography?
What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]
What is the two properties of gravity?
What is the two properties of gravity? Property 1: The gravitational force is a long-range force, which exists between two particles, regardless of the medium that separates them. Property 2: The gravitational force is directly proportional to the product of the mass of the two bodies. This means a larger mass will yield a larger […]
