huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm‚ the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which

"These people want to hurt you. It ’s frightening. You feel like you ’re in a cage out there". Reggie Smith‚ (Berger‚ 1990). Spectator violence at sporting events has been recorded throughout history. People who have power over the events‚ often team owners‚ indirectly influence the amount of spectator violence by encouraging the factors contributing to violence‚ in order to benefit themselves. Sale of alcohol‚ encouraging crowd intensity‚ creating rivalries‚ and targeting social groups‚ are factors

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same‚ but they are not.” Heat and Temperature‚ para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place

It helps to improve the life span of the vegetation and animals living in it. With the rise in wildfires all over the country‚ researchers say that controlled burns will help reduce the risk of catastrophic wildfires. Many people think of fire as only being dangerous and destructive

prepared for the experiment‚ one at room temperature and the other two at 15°C and at 5°C. The room temperature water bath was prepared by filling a basin with tap water about ¾ full so that when the subject’s face is submerged‚ the water will not spill. A thermometer was used in order to obtain the temperature of the water. The temperature obtained was at 26°C. The water baths having temperatures of 15°C and 5°C were also prepared the same way as the room temperature water bath only with the addition of
