Amir took his little sister Erika downtown to buy her a helium balloon for her birthday. As they walked back home in the snow, the balloon shrank. Erika was disappointed. But Amir had just learned about the ideal gas law in chemistry class, and he told Erika that the balloon would be fine. Sure enough, by the time Amir and Erika got home and were taking off their coats, the balloon grew in size.

Amir also told Erika that if she brought the balloon on an airplane ride, it would grow even bigger.

Use this story to answer the following questions.

a. The ideal gas law equation is PV = nRT. What would the ideal gas law look like if the following variables were held constant? (2 points)

i. n and T (Boyle's law) (1 point)

ii. n and P (Charles's law) (1 point)

b. Use the ideal gas law to explain the changes that happened to the balloon. Fill in the table to identify the variable that was changed and the primary effect it had. Indicate if each change showed was related to an increase or a decrease. Some are filled in for you. (8 points)

A. The ideal gas law equation is PV = nRT. The ideal gas law looks as if the variables were held constant -

(i) Putting n and T as constants in the ideal gas equation, we have PV = constant. This is Boyle's law.

(ii) When P and n are constant, we get Charles's law i.e., V = T × constant.

The ideal gas law, also called the general gas equation, is the equation of the state of a hypothetical ideal gas.
It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Benoit Paul Emile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law.
Ideal gas law is a well-defined approximation of the behavior of many gases under diverse conditions.
The ideal gas law is the relationship described by the equation-

PV = nRT

where P is pressure, V is volume, n is the number of moles of an ideal gas, R is the ideal gas constant, and T is the temperature.
