What happens to the average kinetic energy of the particles in a sample of matter as the temperature of the sample is increased? CA. The average kinetic energy decreases.
CB. The average kinetic energy does not change.
CC. The change in average kinetic energy cannot be determined,
CD. The average kinetic energy increases.

i think it is d. e because the next one is igneous.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

catya your not at all which answer i've seen you do this on another question!
