By having no solid matter between the walls (like styrofoam) conduction is eliminated since conduction requires matter to be in contact with other matter. The vacuum state eliminates convection since that is the heating of gas that then carries the energy to another body by traveling there and exchanging heat with it.
Vf = Vi + at
Vf = 0 + (9.80)(4)
Vf = 39.2 m/s down

Standard temperature is equal to 0 °C<span>, which is 273.15 K. Standard Pressure is </span>1 Atm<span>, 101.3kPa or </span>760 mmHg<span> or torr. STP is often used for measuring gas density and volume. At STP 1 mole of any gas occupies 22.4L.
Hope this helps. :)</span>
