Question

Write the equation you would use to calculate the volume of a 5.00 liter sample of air at 50°C when it is warmed to 100°C at constant pressure?

Answer 1

Which of the following would you predict to have a higher electronegativity ... Write the electron-dotformula and predict the shape for the polyatomic ions: ... Joules to warm 55.0 mL water (density = 1.00 g/mL) from 10.0 °C to 100 °C. ... If a sample of gas has a volume of 2.0 L and pressure of 1.0 atm, what is the new pressure ...

Answer 2

PV = nRT

Step-by-step explanation:

The volume expansion of air follows some basic properties of the gas expansion. There are several properties of air that need to be taken into account:

• The volume of air is proportional to the temperature of the air.

The increase in the temperature of the air results in the expansion of the air. This is as a result of the increased kinetic energies of the air particles.

• The number of moles of the gas are the same
• The properties above are expressed by the ideal gas law:

`PV = nRT`

where P = pressure (atm)

n = number of moles (mol)

V = Volume of air (m³)

T = temperature change (K)

R = inversal molar gas constant (atm L/mol K)
