<u>Answer:</u>
There will be No change in volume.
<u>Explanation:</u>
Ideal Gas Equation is used to solve this :
PV=nRT;
P is pressure in Pa,
V is volume in
,
n is number of moles of gas;
R is the universal gas constant, 8.31 J/K mol
T is temperature in Kelvin
when mass is said to be fixed, the number of moles will also be fixed, too. So combining both the constant term n and R which gives
PV=kT
where k is constant.
V= 
So the equation represents that, Volume V will remains unchanged when pressure and temperature are both doubled, therefore the numerator term T and the denominator term P are both gets affected by multiplication of 2, hence by cancellations:
V =
= 
Answer:
Gold, sodium, aluminum
Explanation:
The metals are located on the left side of the periodic table
1 g/cm³ --------------- 0.1 kg/dL
7.86 g/cm³ ---------- ?
7.86 x 0.1 / 1 => 0.786 kg/dL
D = m / V
0.786 = 3.56 / V
V = 3.56 / 0.786
V = 4.529 dL

<em>Answer: The disasters are different according to their occurrence. For example, the causes of an earthquake cannot be the same as that of forest-fire. Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc.</em>
