What happens to the energy level as a substance moves from the solid to the liquid and eventually to the gaseous state?
the amount of motion of each molecule increases. i.e the amount of disorder increases. since the motion is increasing as an object gets converted from solid to liquid to gas, the energy level increases.
If the distance between the spheres is cut in half what is the force between the masses?
The force increases by a factor of 4. If we're talking about gravity, the gravitational force is a function of the masses and the square of the distance between them. As distance decreased by a factor of 2 (since it was cut in half), then the force increases by a factor of 2 squared, and that's 4. Gravitational force increases by a factor of 4 when distance between two gravimetrically attracted objects is decreased by a factor of 2 (cut in half).
What happens to relative humidity when temperature rises?
When temperature rises, the capacity of air to hold water vapor increases. Consequently, the relative humidity decreases because the amount of moisture present in the air remains the same, but it is spread out over a larger volume.
Which planets do not have an atmosphere?
Each of the eight planets has an atmosphere, though you could argue that Mercury in the exception. Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no real atmosphere due to its small size and proximity to the sun.
Which planet has the least amount of craters due to is protective atmosphere?
Venus has a very dense atmosphere, which helps burn up many meteors it pulls in. This lets the planet have many less craters than others. Additionally, the gas giants don't have any known craters, since they are made of mostly gas.
Which gases have increased and decreased from the original atmosphere?
Since the original atmosphere, the gases which have decreased are water vapour and carbon dioxide and the gases which have increased are nitrogen, oxygen
What is the difference between altitude and air pressure?
Air pressure is the amount of pressure exerted by Earth's atmosphere in a specific place, while altitude is the vertical distance of an object or place from sea level. Air pressure decreases as altitude increases, since there is less atmosphere to exert pressure.
Why have the levels of carbon dioxide changed since the early earths atmosphere?
The atmosphere has changed because of population increases and lots of factories that produce the gas. Olivia Perli
Does humidity affect air density?
Yes humidity effects the density of air in a way when humidity increases the air density decreases . the reason behind this phenomena is when the amount water vapor increases the major air content i.e O2 and N2 decreases per volume and since we are talking about air density we say density of air is decreased.
How does burning fossil fuels affect the makeup of gases in the atmosphere?
The overall change in our atmosphere has been about 0.009% since 1800. Most of this change is due to increases in carbon dioxide which now make up about 0.038% of our atmosphere. Much of the rest is due to increases in the level of methane, which has seen a 1 ppm increase.

What is percent of decrease or increase?
A percent of decrease (percentage decrease) is when a value is reduced by a percentage of its original amount. e.g. 100 decreased by 15 percent is 85. A percent of increase (percentage increase) is when a value in increased by a percentage of its original amount. e.g. 100 increased by 15 percent is 115.
What property controls the type and amount of atmosphere a planet has?
gravity controls the amount of atmosphere that a planet has because the more gravity that a planet has, the more atmosphere it can hold in. God controlled the type of atmosphere a planet had at the start, but since then, the chemical reactions on its surface, volcanic activity, and similar things have changed it slightly.

What has happened to farms since the 1950s?
