<u>Answer:</u> The volume when the pressure and temperature has changed is
<u>Explanation:</u>
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
Let us assume:
Putting values in above equation, we get:
Hence, the volume when the pressure and temperature has changed is
Remembering that
d = m ÷ v
d = ?
m = 104 g
v = 21 cm³
Therefore:
d = 104 ÷ 21
<span>d = 4,95 g÷cm³</span>
The answer is c because of going left to right
Answer:
They propagate in materialistic media and non-materialistic media ( space ) .
They propagate in the space at constant velocity , which is 3 × 108 m/s .
They consist of vibrating electric and magnetic fields at certain frequency in phase with each other , perpendicular to each other and perpendicular to the direction of the wave propagation ...
