divide by 2.
x=1,200.
you take the GIVEN MASS of an element, and you put it on top, the coefficient is what it’s over. i believe this is right
Answer:
The new pressure will be 0.225 kPa.
Explanation:
Applying combined gas law:
where,
are initial pressure and volume at initial temperature .
are final pressure and volume at initial temperature .
We are given:
Putting values in above equation, we get:
Hence, the new pressure will be 0.225 kPa.
Answer:
Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
