Suppose you have 2.5 kg of steam occupying 6.5 m^3 at a pressure of 1.013 x 105^ 5 Pa. When the steam condenses to water, it occupies a volume of 0.55 m^3. If the latent heat of vaporization of water is 2.26x10^6 j/kg , what was the change in the water's internal energy? Delta T= 0
m = 2.5 kg
Vi= 6.5 m^3
P = 1.013 x 10^5Pa
Vf = 0.55 m^3
Lv = 2.26 x 10^6 j/kg
Q is coming out of the system w is done on the system w​

c)as speed changes, wavelength and frequency change.

everything changes!

so easy. just google the electromagnetic waves and it’ll pop up.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
