The molecules in an ideal gas at 10∘c have a root-mean-square (rms) speed vrms. at what temperature t2 (in degrees celsius) will the molecules have twice the rms speed, 2vrms?

Phase changes are chemical changes. true or false

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

This is the substance(s) formed in a chemical reaction.
