Metals that do not react with acid would be copper, platinum and mercury
Using the Boyle's law, the volume of the gas at 15 Km is .
<h3>What is Boyle's law?</h3>
Boyle's law states that, the volume of given mass of gas is inversely proportional to its pressure at constant temperature. Since pressure decreases with height, the volume will increase at higher altitude.
Initial volume = 10.0
Initial pressure = 1.00 atm
Final pressure = 0.350 atm
Final volume = ?
Using;
P1V1 = P2V2
V2 =
V2 =
V2 =

Im not really sure but i think its A.<span>It explains the data that relates to the specific problem.</span>
Answer:
The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).
