What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
