Explanation:

1. Charles's Law is the Law that describes how hot air balloons function. Explanation: Because gases expand when heated, a given mass of hot air occupies a greater volume than the same mass of cold air. The density of hot air is smaller than that of cold air.

2. Charles and Boyle's Law applies to aerosol cans. At the same temperature and pressure, equal quantities of all gases have the same number of molecules. Equal volumes of all gases contain the same number of molecules when maintained at the same temperature and pressure.

3. Boyle's law asserts that the product of the pressure and volume of a gas at constant temperature is constant. The pressure cooker operates on the ideal gas law or combination gas law premise, PV = nRT. This essentially indicates that pressure equals volume times the number of moles of a gas multiplied by the gas constant multiplied by the temperature. It increased temperature results in an increase in pressure.

4. Gas laws may be used to predict the behavior of gases. Boyle's law establishes a relationship between the pressure and volume of a gas at a constant temperature and volume. Charles's law shows a connection between the volume and temperature of gas with constant pressure and volume. Temperatures must always be given in Kelvins in gas laws. A barometer monitors the pressure of gas in the atmosphere by the height of a mercury column.   The millimeter of mercury (mmHg) is a unit of gas pressure. A torr is an analogous unit to the mmHg, named after Evangelista Torricelli's creator. The pascal (Pa) is the internationally recognized unit of pressure. Because a pascal is a fairly small measure of pressure, the kilopascal (kPa) is the most practical unit for common gas pressures. 1000 pascals equals a kilopascal.   The atmosphere (atm) is another frequently used unit of pressure. The standard atmospheric pressure, abbreviated as 1atm, is equal to 760mmHg and 101.3kPa. Atmospheric pressure is often expressed in terms of pounds per square inch (psi). At sea level, the air pressure is 14.7psi.

5. The thermometer operates according to Charles's Law. According to Charles's Law, when a gas's temperature rises, its volume rises as well.

The temperature may be determined using Charles's Law by knowing the volume of gas at a certain temperature and applying the formula below. Converting it to the necessary levels for the gas-holding device. This thermometer operates in the same manner as mercury thermometers.
