Answer: A) Forces of attraction and repulsion exist between gas particles at close range.
Explanation:
The <u>Ideal Gas equation</u> is:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
According to this law, molecules in gaseous state do not exert any force among them (attraction or repulsion) and the volume of these molecules is small, therefore negligible in comparison with the volume of the container that contains them. In this sense, real gases can behave approximately to an ideal gas, under conditions of high temperature and low pressures.
However, at low temperatures or high pressures, real gases deviate significantly from ideal gas behavior. This is because at low temperatures molecules begin to move slower, allowing the repulsive and attractive forces among them to take effect. In fact, <u>the attraction forces are responsible for the condensation of the gas</u>. In addition, at high pressures the volume of molecules cannot be approximated to zero, hence the volume of these molecules is not negligible anymore.
The amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline is 8.75 seconds.
<u>Given the following data:</u>
- Acceleration = -0.2
To calculate the amount of time that passes from when this skateboarder begins to slow down until she begins to move back down the incline, we would apply the first equation of motion;
<h3>
The formula for the first equation of motion.</h3>
Mathematically, the first equation of motion for a decelerating object is given by this formula;
<u>Where:</u>
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Time, t = 8.75 seconds.
