A) The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion.
b) Gaseous particles tend to undergo diffusion because they have kinetic energy.
Similar - Both are organic compounds and fossil fuels
Different - natural gas is made up of lighter organic compounds than petrolium
Answer:
combustion reaction, because the products are CO2 and H2O
Answer: The volume of sample at 400 K is 
Explanation:
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
where,
= initial volume of gas = 
= final volume of gas = ?
= initial temperature of gas = 360 K
= final temperature of gas = 400 K
Putting in the values we get:
Thus volume of sample at 400 K is
Answer:
Both resulted in color change.
One involved chemical change while the other involved physical change.
