6. A hot air balloon holds 7.40 x 10 liters of gas. In order for the hot air balloon to rise into the sky, it must
be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon
to land. If the temperature of the balloon is decreased to 40.0°C. what will the new volume of the gas
be?

I need help idk how to do this

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
