What is the meaning of scale division?
The scale divisions indicate the value of measuring units of volume, temperature, pressure, etc.
How does increasing the the temperature of a gas in a closed container causes the pressure in the container to increase?
At the molecular scale, increasing the temperature means that the gas molecules are more energetic and are impacting the walls of the container with more momentum, thus imparting more force to the wall per collision. At the macroscopic scale, the ideal gas law is PV = nRT, which tells us that pressure rises linearly with temperature at constant volume.
When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
Why increasing the temperature of a gas in a closed rigid container causes the pressure in the container to increase?
At the molecular scale, increasing the temperature means that the gas molecules are more energetic and are impacting the walls of the container with more momentum, thus imparting more force to the wall per collision. At the macroscopic scale, the ideal gas law is PV = nRT, which tells us that pressure rises linearly with temperature at constant volume.

Why do you use kelvin?
Because kelvin temperature has a simple relationship with volume, according to Charles's' law if the kelvin temperature becomes doubled at constant pressure the volume of the gas also becomes doubled, this relation is not with Celsius or Fahrenheit temperature.
If the temperature of a fixed amount of gas is increased at a constant pressure what will happen to a volume?
Volume will increase. Think of it this way. If you heat a gas, it gets hotter. When a gas gets hotter, the atoms/molecules are "more active" and the pressure and/or the volume will go up. If your experiment with heating this gas sample must have a constant pressure, then volume will have to increase to give all those "more active" atoms/molecules more play room to prevent the pressure from going up.
What temperature scale places zero at the point where all atomic and molecular motion ceases?
The temperature scale that places zero at the point where all atomic and molecular motion ceases is called the Kelvin scale. On the Kelvin scale, this point is defined as absolute zero, which is equivalent to 0 Kelvin (0K).
What is the temperature scale used with Charles' law?
The temperature scale used with Charles' law is the Kelvin scale. Charles' law states that the volume of a gas is directly proportional to its absolute temperature in Kelvin, when pressure and amount of gas are held constant.
How is the formation of global winds and small scale winds similar?
Winds are caused by differences in air pressure, winds move from high to low pressure. Has something to do with the coriolis effect.:]
Is the volume of water displaced when a golf ball is dropped in a large beaker greater than the volume of the golf ball?
Yes, but only if there is air, dust and other molecular scale debris attached to the ball. In a perfect universe, where nothing but the ball enters the water, then the volume would be exactly the same as that of the sphere.
Why does the mercury move up and down the scale as the temperature changes?
Mercury expands and contracts in response to temperature changes, causing it to rise or fall in the thermometer's tube. When the temperature increases, the mercury expands and moves up the scale, and when the temperature decreases, the mercury contracts and moves down the scale.
