Charles' Gas Law

Convert the following temperatures to degrees Kelvin

a$.25C$

$298*15k$

b$.-45C$

$228*15k$

$228\mathrm{.}15k$

c$.0C$

$273\mathrm{.}15k$

Convert the following temperatures to degrees Celcius

a$.300K$

$26\mathrm{.}85C$

b$.220K$

$-53\mathrm{.}15C$

c$.0K$

$-273\mathrm{.}1C$

$3.$ A $250\mathrm{.}0mL$ sample of air at $100\mathrm{.}0K$ is warmed to $200\mathrm{.}0K$ at constant pressure. What is the volume of the air sample at the new temperature? Show your work below.

$4.$ A $250\mathrm{.}0mL$ sample of air at $100\mathrm{.}0C$ is warmed to $200\mathrm{.}0C$ at constant pressure. What is the volume of the air sample at the new temperature? $($Remember to convert temperatures to Kelvin first$)$ Show your work below.

$5.$ The average kinetic energy of the particles in a gas increases as the temperature of the gas increases. Explain.
