<h2>Hello!</h2>
The answer is: Charle's Law.
<h2>Why?</h2>The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.
The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:
Where,
Also, to describe the relationship between two differents volumes at different temperatures, we have:
Where,
Have a nice day!
Answer: The frequency of this light is
Explanation:
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light =
c = speed of light =
= frequency of light = ?
The frequency of this light is
Answer: Three things are missing:
i) Graph title.
ii) Label for the vertical axis.
iii) The scale and the units for the horizontal axis.
Justification:
1) Find the graph in the image attached.
2) What does the graph represent? You cannot tell because it does not show the tittle.
Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:
Temperature vs. Volume.
3) The vertical axis also must be properly labeled, including the units.
A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.
4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)
