Density is defined as Mass per unit volume of an object ~
And hence, the correct choice is ~ 1
Answer:
NaOH(aq) is a Base.
Explanation:
Those substances which give or release 
ions in aqueous solution are called as the Arrhenius Bases.
In the aqueous solution, NaOH dissociates as follows -
↔ 
If it reacts with a strong acid HCl, the chemical equation for this reaction will be as follows -
It is different everywhere you look but it's mainly asteroid belt <span />
Answer:
Not doubled
Explanation:
The equation below represent the ideal gases relationship
PV ÷ T = constant
Here
P denotes pressure,
V denotes volume,
T denotes temperature in degrees Kelvin
Now
20 ° c = 273 + 20
= 293 K
And,
40 ° c = 313 K
So,
V = Vo. 313 K ÷ 293 K = 1.07 Vo
So, the volume is NOT doubled.
In the case when the temperature would be determined in degrees celsius at 0 degrees so the volume would be zero
