D - density: 1 g/cm³
m - mass: 2,89g
V - volume: ?
----------------------------
d = m/V
V = m/d
V = 2,89/1
V = 2,89cm³

Answer:
A dense substance that is hard and in compressible
Explanation:
I just took the unit review on edge
By there carbon dioxide effecting the air
It would most likely be a observation or hypothesis
Answer:
the question is bogus
see explanation
Explanation:
explain why the pressure in a sealed container of gas decreases when heat is added to the system?
when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!
IT DOES NOT DECREASE
PV =nrT
IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE
THE GREATER T, THE GREATER P
