Science HW part dos

Objective 4

1) The thermal energy particles on a warmer day are moving around more and which causes it to be hotter. The thermal energy particles on a cold day are not as active, therefore it is cold.
2) Ice cream melts on a warm summer day because the thermal particles of the ice cream are not moving quickly, but then the heat from the fast moving particles in the air cause the ice cream particles to move quickly, and then it starts to melt. 
3) Vibrating particles have to do with the boiling point of particles because the hotter the particles get, the faster they move, so when they boil, they are at TOP SPEED. 
4) Condensation occurs when water turns from a gas directly to a solid. This can happen when water vapor touches a cold bottle or glass.
5) Sublimation happens when air saturated with water hits a sudden point of temperature that is below freezing. 

Objective 5

1) In Boyle's law, the relationship described is between pressure and volume. It states that if the volume goes up, pressure goes down, and when volume goes down, pressure goes up.
2) Scientist only half fill high altitude balloons because the higher the pressure is then the smaller the balloon is going to be, so the balloon only needs half as much air as it would in a normal area. 
3) pV=k is the mathematical equation, and the formula is when the amount of volume goes up then the pressure goes down, and when the volume goes down, the pressure goes up.
4) Boyle's law applies to physicians because the temperature of your body also applies to the law so if your temperature goes up your blood pressure goes down and when your temperature goes down your blood pressure goes up.
5) Scuba divers rely on Boyle's law because when the divers go down, their amount of pressure in their tanks and in their body will go up, and it seems that the air tanks are releasing air. Really the air tanks are expanding because when the pressure increases, the volume decreases. Sometimes you can notice this happening with your wet suit too, but it is most noticeable with the air tank.


Objective 6


1) Charles's law is the law that states when volume goes up, temperature goes up, and when volume goes down, temperature goes down too. 
2) quickly
3) Etienne Montgolfier was the first person to fly in a hot air balloon.
