Question

multiple selection! why is the kelvin scale useful for scientific calculations? please select all that apply (2): it can measure the proportional change in quantity for heat when there is a temperature change it helps scientists not do math because there are no calculations involved kelvin rhymes with kevin, which makes it easier to remember like a name it helps scientists not get confused with the positives (+) and negatives (-) when there is temperature change

Explanation:

The Kelvin scale has an absolute zero point, which allows for the measurement of proportional changes in heat - related quantities when temperature changes. Also, since it starts from absolute zero, there are no negative values, reducing confusion about positive and negative temperature changes. Scientific calculations often involve proportional relationships and dealing with temperature changes, making these features useful. The other two options about not doing math and rhyming are not valid scientific reasons for its usefulness.

Answer:

It can measure the proportional change in quantity for heat when there is a temperature change
It helps scientists not get confused with the positives (+) and negatives (-) when there is temperature change
