What are the three main states of matter?

What are the three main states of matter? They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. Can be compressed into smaller spaces? Because there is space between the particles, they can be squashed into a smaller volume when the gas is compressed….particles are fixed to […]

Are temperature and moles directly proportional?

Are temperature and moles directly proportional? At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. What happens to pressure when volume and temperature decrease? […]

How energy is transformed in our body?

How energy is transformed in our body? All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and […]

Is CRT TV bad for eyes?

Is CRT TV bad for eyes? There are two things about CRTs that can potentially damage eyesight. #1 is staring at the same close-range object for hours at a time, causing eyestrain. The muscles that focus the lens are forced to hold one position for a long time, and that can hurt them after too […]

What 4 things are needed for photosynthesis?

What 4 things are needed for photosynthesis? For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun). What are the three end products of photosynthesis? Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is […]

Why are heat islands dangerous?

Why are heat islands dangerous? Heat islands contribute to higher daytime temperatures, reduced nighttime cooling, and higher air-pollution levels. These, in turn, contribute to heat-related deaths and heat-related illnesses such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke. What causes a heat island? How Do Heat Islands Form? Tall buildings […]
