Answer:
Wood
Explanation:
Matter is anything that has mass. Nor sound, fire or electricity have mass which leaves wood as the final answer.
Answer:
the volume will increase
Explanation:
The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .
Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .
Since pressure is also constant , it is volume which will be increased .
It can be explained from universal gas formula as follows
PV = nRT
P , R and T is constant ,
V ∝ n
Volume is proportional to n which depends upon number of molecules .
So volume will increase if number of molecules increases .
Answer:
One atom will give electrons to another atom to fill its shell, this is an ionic bond. The atom giving away electrons becomes positive and the one recieving electrons becomes negative.

Explanation:
CH4 + 2O2 -> 2H2O + CO2
You need to add a 2 in front of the O2 and H2O in order to balance the equation.
