Consider two samples of gas. sample a has pressure p, temperature t and volume v. sample b has pressure p, temperature t/2 and volume v. gas a has the mass of molecule m, gas b has mass of molecule 4m. what is the number of molecules in sample b in terms of number of molecules of sample a, n?

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.

1) estimating temperature to the nearest tenth of a degree

2) estimating the mass of the sample to the nearest tenth of a gram

4) the position of the cups of sand and water under the heat lamp
