Chapter 5, Problem 150CP

a)

Interpretation Introduction

Interpretation:Float of balloon if heated should be explained. Also, factors that change and remain constant should be determined.

Concept introduction:State of any gas is determined by some of its parameters. These parameters are pressure, amount of gas, temperature and volume. Ideal gas law helps to govern state of gas with help of relationships between these gas parameters.

Expression for ideal gas equation for one mole of ideal gas is as follows:

  $PV=nRT$

Where,

• $P$ is pressure of gas.
• $V$ is volume of gas.
• $n$ is number of moles of gas.
• $R$ is universal gas constant.
• $T$ is absolute temperature of gas.
