Air has a lower heat capacity which is the property of a material that describes how much heat energy is required to change the temperature of a substance by one degree Celsius <span />
Chemical should be the answer hope I helped
its c with the older down the older it is
Answer:
The half-life of Material 1 and Material 2 are equal.
Explanation:
Material 1 disintegrates to half its mass three times in 21.6 s, to go from 100g
to 12.5g. That is,
100g - 50g - 25g - 12.5g
Material 2 disintegrates to half its mass three times in 21.6 s, to go from 200g to 25g. That is,
200g - 50g - 25g - 12.5g.
This means that regardless of their initial masses involved, material 1 and material 2 have equal half-life.
Their half-life is 21.6 ÷ 3 = 7.2 sec
Answer:
Na+, O, C, Na
(Na+ has more ionization energy and Na has less ionization energy)
