How do molecules of air in direct contact with Earth's solid, warm surface absorb heat energy? A conduction
B condensation
C. convection
D. diffusion

is diffusion to absorb heat energy

actually its c convection.

Explanation:

my teacher asked the same question but with  diffrent oppstions.

and diffusion is DEFINATALY not the answer. its convection.  

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
