Answer: The mass of aluminium sample is 55.4 gram
Explanation:
As we know that,
where,
= mass of aluminium = ?
= mass of water = 300.0 g
= final temperature =
= temperature of aluminium =
= temperature of water =
= specific heat of aluminium =
= specific heat of water =
Now put all the given values in equation (1), we get
Therefore, the mass of aluminium sample is 55.4 gram
During combustion, chemical energy stored in fossil fuels is converted into KINETIC energy.
That will be 0.78*10 raise to the power of -1 nanometers
Carbonated drinks have the air under pressure so that carbon bubbles are forced into the drink, keeping it carbonated. So when you open a can, the air under pressure in the can comes out of the can at a high speed, making a "whooshing" sound. The gas law that applies to this concept is the Boyle's Law (PV=k or P1V1=P2V2).
