If the heat is absorbed, then the temperature will increase as well.
Answer:
molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled.
Explanation:
Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
Answer:
B. Colloid
Explanation:
Colloid is a mixture that is made up of very small homogeneous particles, thus can not be separated into fractions. Its particles do not settle as other solution, but are evenly dispersed in the medium. Some examples are: liquid milk, jelly, rubber etc
Since colloid is a solution, thus it is made up of two parts; its particles and dispersing medium.
To go from grams to atoms, you first have to convert to moles and them to atoms. To do that, divide the amount in grams by the atomic weight (141.95 in this case) and then multiply by avagadros number (6.022×10^23). After you do all of this, you should get 8.06×10^20.
