Fire transfers heat by CONVECTION, meaning some heat rises, and FALL, meaning some heat goes out in every directions.
Hope that helps!!!
Answer:
increases
decreases
Explanation:
The distance between particles increases when the temperature increases and decreases when temperature decreases.
- Temperature changes in a system causes the particle of such system to behave in different ways.
- When particles gain heat energy as their temperature increases, they begin to move further apart.
- As their temperature reduces they tend to coalesce.
Atomic radio increases as number of valence electrons increase. Hence the first and fourth statement are wrong. Electronegativity is highest for elements on the TOP right hand corner of the periodic table so the third statement is wrong. Hence the answer is the third statement
Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding. When solutes are added to water, they may be affected by the charge distribution.
