What is the effect of temperature and pressure on a gas? The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater […]

Do Low flow shower heads save money?
Do Low flow shower heads save money? Low flow showerheads reduce both water and energy usage, since reducing the amount of water used by the shower will also reduce the amount of energy used to heat it. In doing so, low flow showerheads also reduce the amount of money spent on utilities. Are Low flow […]
Should you land on your toes when running?
Should you land on your toes when running? Landing on the toes distributes the impact of running completely differently than heel striking. Instead of absorbing the impact through knees, toe strikers do so through their ankles and Achilles tendons. Is it better to run on toes or heels? Others claim, that easier form doesn’t mean […]
How is data sent through wires?
How is data sent through wires? Originally Answered: How data is transmitted through wires in the computer ? Most simply, by pulses of electricity. This is a crude analogy, but think of a light switch. You flip it on, and it sends electricity down the wire to the light. Which system uses digital transmission? Which […]
Can a gas change shape?
What would happen if the population of rabbits increased?
What would happen if the population of rabbits increased? There would be more food for the rabbits and slugs, so their populations would increase. However, there would be less food for the frogs and voles, so their populations would decrease. This means less food for the foxes and hawks. How did doubling the rabbit population […]
