Friction because smooth ice provides very little resistance against objects, like ice skates being dragged across its surface.
Answer : The final temperature of gas will be, 149 K
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = 1.55 L
= final volume of gas = 753 ml = 0.753 L
= initial temperature of gas = 
= final temperature of gas = ?
Now put all the given values in the above formula, we get the final temperature of the gas.
Therefore, the final temperature of gas will be, 149 K
The compound that has the element ratio 2:1 is 2H20.
In 2H2O, four atoms of hydrogen react with two hydrogen of oxygen to form molecules of water. Four divided by two will give two, that implies ratio 2;1. This implies that, two atoms of hydrogen will react with one atom of oxygen to give a molecule of water.<span />
The answer would be: <span>dependent on the number of particles
If you see the ideal gas formula you know that volume is directly related to the number of particles.
Closed container volume could influence the pressure that will change the volume but the question seems to talk about open container. If the container is not closed, then the volume of container won't have any effect.
Mass is related to the number of particles, but not directly related to volume so this option is a bit ambiguous.</span>
Answer:
x = 31
Explanation:
-24 = -1x + 7
subract 7 from both sides.
-31 = -1x
divide both sides by -1
31 = x
