What happens at the flat areas of a substance’s heating curve?
both the average kinetic energy of the molecules and the temperature remain the same.
the average kinetic energy of the molecules increases, and the temperature remains the same.
the average kinetic energy of the molecules decreases, and the temperature increases.
both the average kinetic energy of the molecules and the temperature decrease.

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?

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

How will the system respond to a temperature increase?
