Question 19 of 30 A helium balloon's temperature is raised by 1°C. Will this cause its molecules to move faster or slower?
they will move at the same speed
faster
slower​

heating of anything increases the kinetic energy of its molecules, so the molecules will move faster.

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.
