Before you begin note the following notes and tips:

You will use 200 units of substance in all activities.

You can use the ruler to measure volume.

Use tables with proper titles and labels to record your observations.

A. In this part you will keep the volume of the container and amount of substance constant and explore the relation between pressure and temperature.

Pump 200 units of substance and set the constant parameter to Volume.

Part A:

Add heat to the container. What happens to the temperature? Is this what you expected? Explain.

Add heat 5 times and record the values of temperature and pressure and plot P vs. T. What kind of relation do P and T obey? Find the function.

[TIP: for each of the fives times you add heat, record a few values of temperature and pressure and use the averages in your plot]

Part B:

Hit the reset button and again pump 200 units of substance. Set the constant parameter to Temperature.

Note: the height and depth of the container remain constant you can only change its width. Thus, the width of the container can be used as the volume. Explain why this is the case.

Record the pressure for 5 different values of volume and plot P vs. V. What kind of relation do P and V obey? Find the function.

[TIP: For each of the five volumes, record a few values of pressure and use the averages in your plot]

Part C:

Hit the reset button and again pump 200 units of substance. Set the constant parameter to Pressure.

Record the temperature for 5 different volumes and plot T vs. V. What kind of relationship do T and V obey? Find the function.

[TIP: For each of the five volumes record a few values of temperature and use the averages in your plot]

Part D:

What are some conclusions you have made?

Answer 1

A1. As warmth is added to the holder the temperature of the substance of the compartment increments. The temperature increments relentlessly with time. Truly, this is relied upon to happen beacause, heat is a type of vitality and it is moved to paricles in the holder and therefore it's active vitality builds which results in higher speed of particles. The higher motor vitality of particles is deciphered as warmth vitality and the temperature increments with time.

(Volume is set to be 6.3nm^3)

Here P and T are linearly dependent function and has equation of the form y=mx. So, P and T are related by P=cT(under constant volume), where c is a constant.

(Temperature is set to be T=300K)

Here, the volume is taken as the width since tallness and profundity of the compartment are fixed to be some steady esteem. The main variable that would contribute in volume is width,w. In this manner, width w, is taken as the volume itself.

B1. Here the P versus V plot resembles an opposite capacity i.e y=a/x. Subsequently, P and V are connected by P=a/V where, a will be a consistent.
