Answer:
Cooling Steam at 100 C to ice at 0 C
Explanation:
Answer:
It will sink.
Explanation:
Density of water=1gm/cc (In CGS)
Volume of cube=l^3 =3^3= 27cc
Mass of cube =54gm
Density of cube=M/V =54/27 =2gm/cc
Here, density of cube is greater than that of water. So, the cube sinks.
The answer is Silver (Ag)
The temperature in K is 767.4 K
<u><em> calculation</em></u>
This is calculated using the ideal gas equation
that is PV =nRT
where;
P(pressure)= 28 atm
V(volume) = 0.045 L
n(number of moles)= 0.020 moles
R( gas constant) =0.0821 L.atm/mol.K
T(temperature)= ? K\
make T the subject of the formula by diving both side of equation by nR
T =PV/nR
T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)} =767.4 K
