Nitrogen gas consists of _____.
Weegy: You are best allowing air to circulate into a box with the addition of either CO2 or O2, at a slightly higher than normal pressure. You can probably use a sealed aquarium and an aquarium air pump to add air. [ Then add CO2 or O2 from a bottle, you can then tweak the inside pressure to be just over ambient using a small valve of some kind. Aquarium stores should have all the stuff you need. You will also need a barometric pressure gauge inside and out, as well as some method for evaluating the concentration of CO2 and O2 inside and outside the box. You will then spend alot of time tweaking the system, but yuo should be able to get some kind of equlibrium. Remember, you want small increases in concentrations, large increases will just kill everything. ] (More)

This statement is true. Each element consists of only one type of atom.

Elements consist of only one kind of atom and cannot be decomposed into simpler substances.
Our planet is made up of some 90 elements. (Tiny amounts — sometimes only a few atoms — of additional elements have been made in nuclear physics laboratories, but they play no role in our story). Of these 90, only 25 or so are used to build living things.

The specific heat of gold is 0.031 calories/gram C. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 C, how many calories of heat energy were absorbed by the sample?
Weegy: mc?T = Q. [ m = mass: c = Specific heat capacity: ?T = Change in temp: Q = Heat absorbed. 10g x 0.031cal/g/°C x 20°C ?T = 6.2 calories of heat absorbed. (To change to Joules = 6.2cal x 4.184 J/cal = 26 Joules). ] (More)
