The temperature reading of –14°c corresponds to a kelvin reading of

Degrees in Kelvin are always 273 higher than the corresponding celcius degree. Therefore, we just need to add 273 to the celcius degree to find the degree in Kelvin.

-14 + 273 = 259 K

K is the unit of degrees in Kelvin. The answer is 259K.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the correct answer would be d. hope this !
